Telephone Ringing Telephone Ringing Telephone Ringing Telephone Ringing Hi! This is the cardiovascular system. I have a question for you. Go ahead. What is the cardiovascular system? The cardiovascular system includes the heart and the blood vessels.
the heart pumps blood and the blood vessels deliver it
throughout the body. at the center the cardiovascular system is the heart. it is a muscle about the size of your
fist. it is located behind your ribcage and a little to the left of the middle of
the chest. the ribs protect your heart that is why whenever you fall down or
get hit in the chest your heart is safe your.
heart pumps the blood through the body through arteries and veins. these are like little roads your body. the body carries a good nice oxygen and nutrients
that the body needs and carries away the rotten dirty carbon
dioxide and chemical waste, so that the body can
get rid of them. Telephone Ringing Telephone Ringing Telephone Ringing you’ve reached the heart. Yeah mr. heart can you please tell
me more about yourself? Sure let me give it to my operator. the heart divided into the right half and
left half. these two halves of the heart act as
separate pumps each is in charge of pumping blood through one of the two blood vessel circuits. the
heart has four chambers the right atrium, right ventricle, the left atrium and the left ventricle the atria on both sides of the heart
receives incoming blood first and then it send it down to the
ventricles to be pumped out. the right side of your
heart receives oxygen poor blood from the body and pumps it into the lungs to get rid of the carbon dioxide and
to pick up the good oxygen. the left side of your heart receives oxygen-rich blood from the
lungs and pumps it back into your body. the heart depends on four valves to move the blood in your heart in the
right direction. the sound your heart makes comes from the sound of these valves
opening and closing. blood pressure is a measurement of the
force of the blood as it flows through the arteries of the
cardiovascular system. the top number is called the systolic
pressure and is the pressure found in the arteries while the heart muscles are
squeezing blood out of the heart. the bottom number is the diastolic
pressure which is the pressure of the blood as it
continues to flow through the arteries between heartbeats. your heart is the most important organ
in your body. you could not live without a heart and that is why you need to take care of your
heart and keep it really really healthy. these are the main things that you can
do to keep your heart healthy. eat healthy foods, exercise every day, and live life tobacco-free. the digestive system. we all love to eat don’t we? hello you’ve reached the digestive system. can I help you? yes please what is the digestive system? when you eat food it goes into your
digestive system. your digestive system is responsible for
converting the food we eat into energy for our bodies to use. it’s like petrol being put into a car. thank you very much. but what does the digestive system
consistent of? the digestive system includes mouth, esophagus, liver, stomach, gall bladder, pancreas, large intestine, small intestine and the rectum digestion or breaking down of food into
small molecules that will be absorbed into your
bloodstream begins when you put food into your mouth. your teeth help to break the food apart.
00:06:12,510 –>00:06:16,810
saliva helps to soften the food and your tongue helps to push the food into
your throat and down into your esophagus which is a
soft tube that is connected to your stomach. the stomach your little Tummy is a sack that receives the food from the
esophagus. your stomach is located just below the heart. the stomach makes digestive juices which include the acids and enzymes that
help to break our food down into a thick liquid or paste. your stomach is a muscular organ that is able to move in order to mix
the food with the digestive juices. food usually remains in the stomach for
about a couple of hours. from the stomach the mashed up food moves
into the soft long tube known as the small intestine where most of the digestion takes place.
the liver makes a yellowish green fluid called the bile. bile and digested enzymes from the
pancreas help releas the nutrients so they
can be absorbed and circulated around your body in the
bloodstream. the blood bTelephone Ringings the fats, proteins,
vitamins and carbohydrates including the sugars
to the liver which helps make them into building
blocks that the body needs to work and grow. the body does not digest all the food we
eat. the undigested food leaves the small intestine and then
enters the large intestine. the large intestine is about five feet
long, so it is shorter than the small
intestine which is about 25 feet long. but I guess it’s called the large intestine because
its thicker or wider than the small intestine. the undigested food enters the large
intestine in a liquidy paste. in the large
intestine water is removed from the liquid
paste turning what is left into solid waste. the solid waste then collects in the rectum at the end
of the large intestine. the solid waste will finally leave the
body through an opening called the anus and this is what happens when you poop. keep your digestive system in good shape
by eating lots of healthy food. like a lot of fruits and a lot of vegetables. greasy or fatty foods like fast food can
be difficult to digest. so try to eat these foods in moderation and don’t forget you must drink
lots and lots of water. when you take care of your digestive
system it will do you right. The respiratory system. we breath in order to take good nice yummy oxygen into our bodies and get rid
of the dirty rotten carbon dioxide. I’m breathing hard. are you? Hello you have reached the respiratory system. can I help you? yes please. what is the respiratory system? your respiratory system is made up
of the organs in your body that help you breath. you breath so that you can deliver oxygen
into your body and take away carbon dioxide. thank you very much. breathing is all
about knowing the respiratory system. so what is the respiratory system
made up of? the respiratory system is made up of the trachea, the lungs, and the diaphragm. how does the respiratory
system work? in when you breath in air you bTelephone Ringinging oxygen it goes into your
lungs and when you breath out you blow carbon
dioxide out. the diaphragm is a muscle beneath the
lungs that helps move air in and out of your
body. when you breath in the diaphragm contracts pulling air in through your nose in your mouth
through the trachea inflating the lungs just like a baloon. when you breathe
out the diaphragm relaxes and moves up to help pushed air out of
your lungs out of your nose and mouth. the air you breathe passes into smaller
tubes that branches within the lungs. these tiny tubes are called bronchioles and there are about thirty thousand
of them in every lung. their tiny air sacs called alveoli at the ended each bronchioles. there are about 600 million alveoli
in your lungs. you don’t believe it. do you? oxygen in the air you breathe passes through the walls at the alveoli
into very small blood vessels called a capillaries then the oxygen-rich
blood is pumped throughout your body and the carbon dioxide that is produced
by the body moves in the exact opposite way passing
from the capillaries into the alveoli and leaving the
body when you breathe out. it looks simple doesn’t it? well that is what breathing is all about. how to love your lungs the best way
to keep your Lungs pink and healthy is not to smoke. you can also
show your love for your lungs by exercising. As you breathe more deeply and
take in more air, your lungs become stronger and
better, at supplying your body with the air it
needs. keep your legs healthy and they
will thank you for life. nervous system tasting, smelling, seeing, heaTelephone Ringing, thinking, moving, dreaming, breathing, heartbeating, running, feeling, pain or
pleasure, laughing, sleeping, singing, remembeTelephone Ringing, you couldn’t do any of these things without
you’re nervous system. Telephone Ringing Hello! this is the nervous system. how are
you doing today? I’m doing alright. I just want to know
more about the brain or the nervous system. so what is the nervous system made of? the nervous
system is made up of brain the brain is a jelly-like
substance. it manages the body and yet weighs teeny weeny 1.5 kilos or just three
pounds. spinal cord. the nerves of your body the brain communicates with the rest of
the body through the spinal cord and nerves. they tell the brain what is going on in
the body at all times. this system also gives
instructions to all parts of the body about what to
do and when to do it. it is called the nervous system because it is made up of billions of nerve
cells that can be found in the brain which is the control center of the nervous system. your brain is divided into two sides. the left side of your brain controls the
right side of your body and the right side your brain controls
left side of your body. let’s take a look at some of the important
parts of the brain. The Cerebrum. the biggest part of the brain is
cerebrum. the cerebrum makes up eighty-five
percent of the brains weight and it’s easy to see why. the cerebrum is the thinking part of the
brain and it controls you voluntary muscles. the ones that move when you want them to so you can’t dance or speak or play soccer without your
cerebrum. the cerebellum. next up is the cerebellum. the cerebellum is at the back to the brain
below the cerebrum. it’s a lot smaller than the cerebrum . well morning but it is a very important
part of the brain. it controls balance movement and
coordination because of your cerebellum you
can stand straight keep your balance and move around. the thalamus. the thalamus
carries messages from your sensory organs. when you smell a yummy curry
or paneer tikka, that is the time thalamus works. the brain stem. controls breathing, heartbeat and digestion. it also connects
the rest to the brain to the spinal cord. so the brain is boss. but it can’t do it alone it needs some
nerves actually a lot of them and it needs a spinal cord which is a
long bundle of nerves inside your spinal column the vertebrae that protects. it is the spinal cord and nerves that let messages flow back and forth
between the brain and body . ouch! That hurts. brain is the boss so what can you do for
your brain. well there’s lots of things for you to
do. eat healthy foods that contain potassium and calcium. these
two minerals are very important for the nervous.
system exercise get a lot of play time. use good
protection wear a helmet when you ride your bike or play other sports that require head
protection. don’t drink alcohol or take drugs or use tobacco and most important use your brain use. your brain by
doing challenging activities such as puzzles, reading, playing music, making art or anything else that gives your
brain a workout the urinary system. the urinary system makes sure you get
rid of all the dirty waste and the excess fluid in your body. Telephone Ringing Telephone Ringing Telephone Ringing Hi! This is the urinary system. How can I
help you today? Yes please. what is this thing called the urinary
system? the organs tubes muscles and nerves that work together to create store and
carry urine is the urinary system. but don’t these
organs and tubes have any name? sure they do. the main part of the urinary
system are the kidneys. the kidneys are bean
shaped organs about the size of your fist. they are near the middle of the back just below the rib cage. the uteters. tubes leading from the kidneys to the
bladder the bladder. the bladder is a hollow muscular organ shaped like a big balloon and the urethra a tune leading
from the bladder to the exterior of the body. the kidneys filter the blood and remove waste producing a
liquid called urine. some people call it pee . but remember the cleaned blood least
kidneys and travels throughout the body. each kidney has millions of urine
making units known as Nephrons that filter the blood that flows through the kidnies. after the
Kidnies do their thing, the urine is carried by two thin tubes
called you ureters down to the bladder. the ureters are
about 8 to 10 inches long. muscles in the ureter walls constantly tighten and relax to force
urin downwards away from the kidnies. small amounts of
urine are emptied into the bladder from the
ureters about every 10 to 15 seconds. the bladder is a storage sack that holds the urine when the bladder is
about halfway full your body tells you to go to the
bathroom. then the bladder muscles go into action and the urine is released from the body
through a tube called the uretra. let me tell you something that is really
interesting. about a 150 liters or thirty three
gallons of fluid pass through your kidneys every day but 99
percent of this is cleaned and goes back into your blood. so I guess
that it is very important to try to take care of the urinary system. it is very well-known that aging taxes the urinary system but a person can lessen the effects of
aging on the urinary system just like every other system in the body
by following a healthy lifestyle. This includes rest, drinking lots of water, no smoking, no alcohol, proper diet, and exercise regularly. the immune system. I’m not feeling good
today. let me call the immune system to find out
more. Telephone Ringing Telephone Ringing you have reached the immune
system. how can I help you today? I’ve heard about the immune system and I
would like to know more about it. the immune system is our body’s defense
system. the immune system is made up of a complex
and vital network of cells and organs that protect the body from infection. The purpose of the immune system is to
keep all the infectious dirty rotten
micro organisms such as certain bacteria viruses and fungi out of the body and to destroy any infectious
micro organisms that do dare invade the body. thank you very much. hold on hold on there is a lot more to this the organs
involved with the immune system are called the lymphoid organs which
effect growth development and the release of lymphocytes. lymphocytes a type of infection
fighting white blood cell that are produced in the bone marrow. the blood vessels and the lymphatic vessels carry the
lymphocytes to and from different areas in the body. each
lymphoid organ helps in the production and the activation
of lymphocytes. lymphoid organs include of adenoids, two glance located at the
back of the nasal passage. appendix, small tube that is connected to the large
intestine. blood vessels, arteries veins and
capillaries through which blood flows. bone marrow, soft fatty tissue found in bone cavities and lymph nodes, small organs shaped like beans located throughout the body and connect
via the lymphatic vessels lymphatic vessels, network of channels throughout the
body that carries lymphocytes to the lymphoid
organs and the bloodstream. Peyer’s patches, is a lymphoid tissue in the small
intestine. spleen is a fist-sized organ located in the abdominal cavity. Thymus these are two lobes that joining
in front of the trachea behind the breastbone. tonsils two oval masses in the back of
the throat. once the lymphocytes are initially
formed, some will continue to mature in the bone
marrow and become B cells. other lymphocytes will
finish their maturation in the thymus and become the T cells. B
and T cells are the two major groups of lymphocytes which recognize and
attack infectious microorganisms. everyday your immune system does a
battle to keep you healthy and make you feel at
your best. you need to try and take good care of it. here are some tips. proper diet, regular exercise, adequate sleep, control stress, the endocrine system. glands are organs that run the endocrine
system. Hello! This is the endocrine system. How may
I help you? can you tell me what the endocrine
system is all about? the endocrine system is a collection of
glands that produces hormones which are
necessary for normal bodily functions this is a complex system. keeps your body growing developing and
working the way it’s supposed to. glands are small organs located
throughout your body that releases substances called the
hormones. these hormones influence almost every
cell, organ and function of our bodies. each
type of gland has its own special function. for example, they help in regulating mood, growth and
development, tissue function and metabolism as well
as sexual function in reproductive processes. the major glands that make up the human
endocrine system are pineal gland. the pineal gland is located
in the middle of the brain. it secretes a hormon that may help
regulate the wake sleep cycle. pituitary. allthough it’s no bigger than a little Pea, the pituitary gland located at the base
of the brain is considered the most important part
Endocrine system. it’s sometimes called the master gland. because it makes hormones that control
several other endocrine glands. hypothalamus. the hypothalamus links
the nervous system to the endocrine system via the pituitary
gland. the hypothalamus also controls body
temperature hunger and thirst. Thyroid. the thyroid gland located in
the front part of the lower neck is shaped like a butterfly and usually
weighs less than one ounce. the thyroid gland controls the
rate at which the body produces energy from nutrients. thyroid hormones also play a key
role in the bone growth and the development of the brain and
nervous system parathyroids attached to the thyroid are 4 tiny that function together
called the parathyroids. they release parathyroid hormone which regulates the level of calcium in
the blood the parathyroid glands located behind the thyroid controls the
level of calcium in the blood. calcium of course we know is very very
important, not only for the bones and the teath but
also for nerve functioning, muscle contraction, blood clotting and
glandular secretion. adrenalines. these are the
triangle-shaped glands that sit above the kidneys. they are chiefly responsible for regulating
the stress levels. taking care. keeping the endocrine
system healthy healthy diet and exercise regular. the system of the body respond well to a healthy diet and regular exercise
and the endocrine system is no exception. reduce stress, combining exercise with
proper amounts of asleep relaxation techniques and lots of
positive thinking helps reduce stress and keeps the
hormone levels balanced. the skeleton system. everyone has a skeleton. it’s what makes
you the shake you are. this is made up of lots and lots of bones an amazing 206. half of these are in the hands and feet. Telephone Ringing Whats up? Yes please! I have always wondered what the skeleton
system is made up of? the skeletal system is what keeps your
body in shape, protects her vital organs such as the
heart brain and lungs and enables you to move. let me tell you something more about
bones. when you were a teeny, weeny baby. you
have tiny hands, tiny feet and tiny everything. slowly as you grew older everything became a
bit bigger including your bones. a baby’s body has about 274 bones at Birth. these eventually fuse or grow together to
form the 206 bones that adults have. these eventually fuse or grow together
to form the 206 bones that adults have. by the time you are
about 25 this process will be complete. after this
happens there can be no more growth. these bones are
made as they ever will be all these bones
make up a skeleton. let’s take a look at some of the major
bones starting at the top. the skull. the skull is the bony section
of the head. the skull protects the brain and provides
attachments for muscles of the head and neck. the cervical vertebrae. these are the seven vertebrae of the
spine that form the connection to this skull and
the neck. the clavicle. the clavicle is the collar bone. the
sternum is the breastbone a long narrow flat bone that forms the center of the
front at the chest. the humerous. the humerous is a long bone in the upper arm that runs from the shoulder to the elbow.
the vertebral column or spine. the spine is a column of bone and
cartilage that extends from the base of the skull
to the pelvis. the spine is made up of approximately 33
bones called vertebrae. it enclosed and protects the spinal
cord and supports the trunk of the body and
the head the Ribs. ribs are flat curved bones that form
the framework of the chest and makeup a cage to protect the heart
and lungs. there are twelve pairs of Ribs each joined at the back of the cage to a
vertebra in the spine. the radius is the shorter the two forearm bones. the
ulna. the ulna is the longer of the two bones of
the forearm. the pelvis. the pelvis is a symmetric Telephone Ringing of bones at
the base of the spine. it also provides support for the rest
the body above it. it protects abdominal organs such the
bladder, rectum and in women the uterus. the femur. the femur is the thigh bone, the longest
bone in the body. the patella. the patella or kneecap is a triangular shaped bone
at the front of the knee joint. the tibia. it is also called the shinbone. the tibia is the inner and thicker of the two long bones in the lower leg.
the fibula. the fibular or the calf bone is the outer and
thinner of the two long bones in the lower leg. phalanges the phalanges are the small
bones that make up the fingers and the toes. taking care of bones. your bones help you out
every day. so make sure you take care of them.
here’s some tips. drink milk and eat other dairy products
strengthen your skeleton by drinking milk and eating other dairy products like low-fat
cheese, frozen yogurt. they all contain calcium
which help bones harden and become really strong. being active. this is another way to
strengthen your bones is through exercise like running, jumping, dancing and playing. wear the right protective equipment wear.
a helmet when you ride a bike or wear the right helmet when you play
sports. the muscular system. one of the most amazing things about the
human body is the incredible range of movement and mobility it has. Telephone Ringing Telephone Ringing Telephone Ringing what are the functions of the muscular
system? muscles perform four important body functions.
maintains bodies posture, stabilize joins, provide movement, so that we can move whenever we want. this day to day activity is accomplished
by our muscles through the extraordinary and facinating
ability of converting chemical energy energy
stored in nutrients into mechanical energy, energy in movement. they also help move food from one organ
to another. maintaining body temperature. By generating heat that the body
requires. Wow! that’s great. but how many muscles
do we have? you have more than 600 muscles in your
body. but there are three different kind of
muscles in your body. smooth muscle, cardiac muscle, and skeletal muscle. smooth muscles are found in the body
organs and are at work all over your body. these muscles are also called
involuntary muscles, because you can’t control this type of
muscle. your brain and body tells these muscles
what to do without you even thinking about it. for example, in your stomach in the digestive system
these muscles contract tighten up and relax to allow food to
make its journey through the body. this way you do not have to focus on
digesting your food. it happens all by itself. cardiac muscle. the muscle that makes up
the heart is called cardiac muscle. just like smooth muscles these are also involuntary muscles and work all by
themselves with no help from you. this way we do not think about a
heartbeat constantly. think how bad it would be to have to
consciously and constantly tell your heart to beat and what if you forget. Ooh! you see, cardiac muscle. Hurray! the thick muscles
of the heart contract to pump blood out and then
relax to let blood back in after it’s circulated
through the body skeletal muscles. the skeletal muscles are the only
voluntary muscles of your body. which means you can control what they do the skeleton
muscle covers the bony skeleton and together to give your body power and
strength skeletal muscles come in many different sizes and shapes to allow them to do many types of jobs.
these are the kind of muscle you think of when we say muscle. the skeleton muscle shows how
strong you are and also allow you to control your body
movements. for example, you kick the soccer ball
into the goal exercise and weight training can help
you increase the skeleton muscle size. keeping the muscular system healthy. here are some tips:
exercise, aerobic exercises help to strengthen
the heart and lungs you can walk you can cycle you can swim you can run and climbing stairs can be
really fun. for example, walking, jogging, cycling, swimming and climbing
stairs are just a few examples of aerobic
activity. exercise that increases the size and
strength of muscles are called anaerobic exercises. example strength training or weightlifting and
sprinting. when combined with exercise the
following also help the muscular system. proper nutrition. leafy vegetables and
whole grains and yummy fruit. drinking enough water, adequate rest and stress reduction and no tension. Hey Folks! Did you enjoy learning about how our fabulous human body works? I’m sure
you loved it. imagin understanding something
that is there in us which was always with us from the day we
were born. such an important thing to now well. hope you had fun and catch you next time
