A Real Trip
Umm, this pizza is good, and the crust is especially chewy and crispy. I think I need a little more saliva from my salivary glands to help wash this down! Chew, chew, chew, now that's better, little pieces are much better to digest than big pieces, and they float down the esophagus much better, too. What's that I feel? It's the chemical enzymes in my saliva, already acting on the chewed food to break it down before it begins the long journey through my body....what a trip! Oh, the enzymes cool my food too, so it doesn't burn my stomach when it arrives.After I chew my pizza, it travels down the esophagus, past the trap door (epiglottis) that makes sure my already digesting pizza doesn't take a side trip to the lungs, and mixes with more enzymes as it flows down the tube to the stomach, otherwise known as the esophagus. It's muscular, yet flexible, just like me...oh, I digress. As I swallow, the esophagus contracts, or undergoes peristalsis, moving the food right along to the stomach. I'm a big eater, and luckily, my stomach
There, my little molecule of crust, already converting into sugar by the amylase enzymes, and now, it mixes with the digestive enzyme called hydrochloric acid (HCL), or in the biz, "gastric juice. Then, it's out of the body to make room for more pizza! (Yes, pizza for breakfast is a good way to start the day, and start the process all over again. Sphincter and is flowing through the small intestine. Now, my little molecule becomes part of the chyme, the liquid form of food and acid that starts the journey through the intestines. Pepperoni and cheese, in another, less desirable form, end up in the toilet bowl tomorrow, after they pass through the large intestine. Good thing, this is an extra-large pizza. The maltose breaks down further in the intestine into a glucose (sugar) called maltose. But what about my friends, pepperoni, cheese, and pizza toppings? Some of them just don't digest. Pyloric Sphincter keeps the opening between the stomach and small intestine clear and flowing nicely, and soon my little molecule has said goodbye to Mr. For maltose to break down into glucose, a lot of other organs get involved, like the liver, which produces bile that helps emulsify fat molecules into smaller molecules that will digest or pass through the body. Most of the remaining water in my friends gets adsorbed here, and then they decompose with the help of bacteria in the intestine. It's not all that easy, you know. Nutrients diffuse into the blood stream and with blood are delivered to the rest of the body. If my body needs energy, then it will use the glucose for a quick burst, otherwise the glucose can get stored as fat.
