The area around the anus, inside and outside the body, is called the anal region. It is made up of the anal canal and the perianal skin.
Perianal skin @(Model.HeadingTag)>
The perianal skin is the skin around the anus. The perianal skin is made up of squamous cells and is similar to skin found anywhere else on the body.
The anus is the end of the gastrointestinal tract. Your body feels the urge to have a bowel movement when nerves in the muscles of the rectum and the anus signal that the rectum is full. The muscles of the internal anal sphincter relax and the poop moves from the rectum into the anal canal. Once the external anal sphincter relaxes, the poop leaves the body through the anus.
