The StorY oF DiGesTive sYsTEm......

Wow! What a roller coaster! I never knew digestion would be such an agitating process. First, we were chewed up by the teeth. Some enzymes joined us in the mouth, but they weren’t very nice. They kept trying to break us down, and some of the glucans I was bonded to were pulled away.

Next, we went down a long tube called the esophagus. The muscles in the walls of the tube were very pushy! We were then admitted into the stomach by a valve called the Sphincter. He was kind of paranoid, and did not let us through until he was sure there was enough room for us. Inside the stomach, it was very dark. All of a sudden, these glands started releasing slimy mucus, water, and strong acid on us. I was pretty scared because I couldn’t see what was going on, and I only had one glucan who was still bonded to me to talk to.

After about four hours in that horrible stomach, the muscles in its walls finally pushed us on to part of the small intestine called the duodenum. At first, I thought this organ was going to be much better because the intestinal juices started to neutralize those strong stomach acids that were hanging around us. Soon, however, some more glands started letting loose pancreatic enzymes, which were even meaner than those stomach juices. Some guy named Amylase came and broke the bond between me and the other glucan, so now I’m not even part of a disaccharide anymore.

When we had all been broken down into simple sugars again, we were pushed on into the small intestine. The walls of the small intestine were covered with little finger-like projections called villi. There were so many that they looked like a pink carpet. Then, the whole organ started churning so much that I thought I was going to be sick. I looked for a way out and was able to pass through the walls of one of the villi into a capillary. I was so glad to get out of those disgusting organs! Now the blood in the capillary is carrying me along to my next destination. It’s not a bad way to travel, so I might as well go with the flow!


An interesting and meaningful article which found from internet explaning feeling of "Carbohydrate" travelling in humans' digestive system....
