<P> The human anus ( from Latin anus meaning `` ring '' , `` circle '' ) is the external opening of the rectum . Two sphincters control the exit of feces from the body during an act of defecation , which is the primary function of the anus . These are the internal anal sphincter and the external anal sphincter , which are circular muscles that normally maintain constriction of the orifice and which relaxes as required by normal physiological functioning . The inner sphincter is involuntary and the outer is voluntary . It is located behind the perineum which is located behind the vagina in females and behind the scrotum in males . </P>
