How the Digestive System Works

The digestive system begins at the mouth and ends at the rectum and anus, where solid waste is expelled from the body after water and nutrients have been absorbed.

The inside of the anus is lined with glands and four to six crypts, or pockets. Several muscles ring the anal canal and work together to control bowel movements. The inner muscle, just beneath the lining of the anal canal is called the internal involuntary anal sphincter. This muscle is usually contracted to close the anal canal.

Only a physician can make an accurate diagnosis of what is causing the symptoms. Some anorectal disorders, such as abscesses, can be lead to cancer of the colon, anus or rectum.
