Well, you eat stuff. Once you eat stuff, you get energy. After you eat stuff and receive energy, you excrete that stuff back out, minus the energy you took from it.
Digestion.
The stomach and the small intestine are the most important part for digestion. You CAN NOT live without a small intestine, since most nutrients are also absorbed from there also.
The esophagus joins the throat and stomach in the digestive system. No digestion occurs in the esophagus; its only function is transport.
The function of the crop in the digestive system of the the bird is to temporarily store food for later digestion. In seed eating birds the crop is like a pouch in the esophagus and no real digestion occurs there it occurs in the gizzard which grinds it all up.
Absorbtion of proteins occurs in the small intestine. Digestion starts in the stomach.
It occurs from the stomach through the small intestine.
Some chemical digestion of carbohydrates occurs in the mouth with salivary amylase. Most chemical digestion occurs in the duodenum of the small intestine.
I do not believe so. Excretion occurs after digestion. Digestion is after food has been eaten, then the digestive track picks out what the body needs to store, and the junk is thrown out. The ''junk'' enters the excretory system and the excratory disposes of it. Actually the toilet does.
