Hello I'm a tarantula that is full of protein, salt, and lipids. Im going to be eaten by Ted Bundy.
Im now entering his mouth where i will be mechanically digested with chewing and then i will be pushed down the esophagus by waves of muscle movements called peristalsis
Now that im in the stomach i am being chemically digested and my proteins will be absorbed by pepsin.
Now after the stomach im in the small intestine where small ribs on the intestine walls called villi are mechanically digesting me and where most of the enzymes that take my macro molecuels are absorbed to be used in cells. My sodium is also digested.
Now in large intestine the water used in my digestion is taken back out and the rest of my nutriments are absorbed
With all my important nutrements absorbed i will leave the body through the rectum that is a part of the large intestine. The opening where i leave is called the anus, but the rectum and anus do not digest anything they just help waste leave the body.
