Anal canal
Functional segment of the large intestine
Anal canal
The anal canal is the part that connects the rectum to the anus, located below the level of the pelvic diaphragm. It is located within the anal triangle of the perineum, between the right and left ischioanal fossae. As the final functional segment of the bowel, it functions to regulate release of feces by two muscular anal sphincter complexes. The anus is the aperture at the terminal portion of the anal canal.
