Explanation:

There are two major muscles the stool must pass through to exit the body, the internal sphincter muscle and the external sphincter muscle (4). The internal sphincter muscle is “involuntary”. ... In fact, squeezing the external sphincter muscle pushes the stool out of the anal canal (5) and the rectum relaxes.
