  • KidsHealth presents: How the Body Works.

  • With Chloe and the Nurb.

  • I see your gall stones and raise you four tonsils.

  • Call! What do you got? Read em and weep.

  • A pair of kidneys!

  • Well, filter my trash. Too bad for you

  • I have a straight set of teeth.

  • Argh. 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.

  • It's a mouth!

  • Nurb, let's get out of here! I can't. I'm paralyzed with fear.

  • Burp

  • Chloe, wake up. What? Where are we?

  • We're in the mouth, the gateway to the digestive system.

  • The digestive system? Yep. 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

  • Ahhhh! 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.

  • Looks like we're in the esophagus,

  • a tube that runs from your mouth to...

  • the stomach!

  • 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?

  • Yes, siree. Gastric juice isn't like orange or grape juice.

  • Your stomach secretes a mix of acid 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? You've seen this combo of chewed up food and gastic 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 in the rainbow.

  • Blah!

  • I think it's time to move on to the small intestine.

  • Here we are. The first part of the small intestine is called the duodenum.

  • And it's where liquified food goes next. Duodenum. Duodenum.Duo-denum!

  • There are more digestive juices found here, like bile.

  • Bile is made in the liver and stored in the gall bladder 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!

  • Welcome to the large intestine!

  • Hold on. If the small intestine does all that,

  • why do you even need a large intestine?

  • 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.

  • Poop!

  • Nurb, what's that sound? Uh-oh.

  • 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.
