The intestine has three functions:
The first is to digest food that is eaten.
The second is to absorb water, electrolytes and nutrients.
The third is to help get rid of wastes from the body.
It starts at the opening of the stomach and ends at the anus or rectum.
The intestine is a long, slender, coiled tube. The first part is called the small intestine and the last part is the large intestine.
The small intestine is further divided into the duodenum, jejunum and ileum.
The large intestine is divided up into the ascending colon, transverse colon, descending colon, sigmoid colon and rectum.
Together, the small intestine (20 feet) and large intestine (5 feet) are about 25 feet long.
