Where does the food that leaves small intestine end up and how it get there?

The food that leaves the small intestine ends up in the large intestine (colon). It gets there through a process called peristalsis, which is a series of involuntary muscle contractions that move food through the digestive tract.

Peristalsis begins in the esophagus and continues through the stomach and small intestine. In the small intestine, peristalsis is particularly strong and helps to mix food with digestive enzymes and absorb nutrients. Once the nutrients have been absorbed, the remaining food waste moves into the large intestine.

The large intestine is responsible for absorbing water and electrolytes from the food waste, and for forming it into stool. Stool is then stored in the rectum until it is passed out of the body through the anus.
