Bowel scope – image description

This illustration shows an outline of the bowel within a person’s body. It shows the different parts of the bowel including the sigmoid colon leading to the rectum (also called the back passage) and the anus. Within the bowel is a narrow, flexible tube called a sigmoidoscope with a light on the end. It passes from outside the body through the anus and back passage into the sigmoid colon. It stops part of the way into the sigmoid colon.
