A Piece of Mushroom


I am a piece of mushroom. I contain a lot of carbohydrates, Vitamin C, B6 and D, proteins etc. I am low in saturated fat and sodium. I was placed on a plate, facing a young girl seemed bothered. She played with me with her fork for a while, and stabbed me hard and put me in her mouth. She chewed me several times and I was separated into several small pieces called boli, covered with saliva. The little girl swallowed and immediately drank a mouth full of water. As the girl swallowed, the epiglottis automatically closed and stopped the boli from going into airway tube to avoid choking the girl. My body parts passed through the pharynx into esophagus which is a tunnel that transports food into the stomach. The muscles in the esophagus pushed me down as a process called peristalsis. Later, I was in the stomach covered in gastric juice which is acidic. The pepsin, an enzyme (a protein found in human body that helps speeds up reactions) presented in gastric juice breaks down the boli into liquid, called chyme. If I were a kind of liquid already, it wouldn’t be so complicated. I traveled as chyme through the first meter of the small intestine called duodenum. My nutrients got absorbed by the villi on the wall of the small intestine. Villi cover the inside of the small intestine to increase surface area to fasten the absorption rate. If I was fried-chicken or corn, I would have became feces and been stored in the rectum until eliminated through the anus. However, fortunately, I am very easy to digest, so I became urine, which was stored in the bladder. I waited for a while until the bladder was full and was eliminated through the urethra.
