How the Digestive System Works

How the Digestive System Works


KidsHealth presents
“How the Body Works,” with Chloe and the Nurb. [MUSIC PLAYING] I see your gallstones and
raise you four tonsils. Call. Whatcha got? Ha! Read ’em and weep–
a pair of kidneys. Well, filter my trash. Too bad for you, I have
a straight set of teeth. Arr! Stupid, good-for-nothing cards! I curse the day I bought you. Double or nothing? Nurb, did you eat chili again? That’s not me, Chloe. [BELCH] It’s a mouth! Nurb, let’s get out of here! I can’t. I’m paralyzed with fear. Arr! [BELCH] Chloe, wake up. Wha– where are we? We’re in the mouth, a gateway
to the digestive system. The digestive system? Yup. It takes the food you eat,
breaks it down, and turns it into energy you can use. It’s trying to break us down
into tiny pieces as we speak. Aah! Oh, don’t worry, Chloe. That’s why we’re wearing these
spiffy anti-digestive suits. Nurb, what’s this
goop on my arm? Oh, that’s saliva. As soon as you take a bite
of food, digestion begins. Saliva contains things
called enzymes that start breaking down food immediately. Whoa! Looks like we’re in the
esophagus, a tube that runs from your mouth
to– the stomach. Yeowtch! Oh, happy day! Food! Now we can watch it be digested. Lucky us. Look at the food. Look at it! Right here in the
stomach, gastric juices are starting to break it down. It’s amazing! Gastric juices? Yessiree! Gastric juice isn’t like
orange or grape juice. Your stomach secretes a
mix of acids and enzymes that start digesting
the food you eat. The stomach also churns the
partially-digested food, turning it into a
lovely, liquidy mush. Then the food moves into
the small intestine. Bye bye, handsome. Handsome? That combo of chewed-up food
and gastric juices was gross. Well then, you’re gross. Excuse me? Whoa, you’ve seen this combo
of chewed-up food and gastric juices erupt from your own
body if you’ve ever thrown up. Oh. I have seen that before. Nurb vomit sparkles with all
the colors of the rainbow. [MUSIC PLAYING] [VOMITING] [VOMITING] I think it’s time to move
on to the small intestine. Whoa! Here we are. The first part of
the small intestine is called the duodenum and it’s
where liquefied food goes next. (SINGING) Duodenum,
duodenum, duodenum! There are more digestive
juices found here, like bile. Bile is made in liver and
stored in the gallbladder until your body needs it. Bile and enzymes
from the pancreas break down the proteins,
fats, and carbohydrates. It’s here that the body absorbs
the vitamins and minerals from the food. Whoa! [MUSIC PLAYING] Welcome to the large intestine! Hold on. If the small intestine
does all of that, why do we even need
a large intestine? Oh ho ho, my dear
Chloe, of course you need a large intestine. The large intestine
has an important job– to absorb water and salt. So what’s left? At the end of the
digestive process, anything that
hasn’t been absorbed is considered waste,
which your body doesn’t need– in other words, poop. (SINGING) Poooooop! Nurb, what’s that sound? [RUMBLING] Uh oh. Whoa! Whoa! How am I going to tell
my diary about this? Just say, “Today, me and my best
buddy Nurb went on a journey through the digestive
system, and we had the time of our lives.” Uh, OK. [MUSIC PLAYING]
