Large Intestine and the Anal Canal

About the Large Intestine and the Anal Canal

The large intestine is the final part of the digestive system. Its main functions are to absorb water and electrolytes from intestinal contents and to form and eliminate stool.

The anal canal is the final segment of the digestive tract. It controls bowel movements through coordinated muscular and nerve mechanisms.

Normal function of this part of the digestive system is essential for general well-being. Disorders affecting it may cause changes in bowel habits, pain, bleeding, or discomfort in the anorectal area.
