Rectum

 

The rectum is almost always empty since when it is filled with fecal material, defecation must follow.  At the junction between the rectum and the sigmoid colon there is a functional sphincter which is augmented by the angulation between the two structures.

Mass movement of fecal matter from the colon enters the rectum and causes reflex contraction of the rectum with relaxation of all sphincters.
