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.
