Article Excerpts about Rectum

As food moves through it, the colon absorbs water while forming waste products, or stool. Muscle contractions in the colon push the stool toward the rectum. By the time stool reaches the rectum, it is solid because most of the water has been absorbed. (Source: excerpt from Constipation: NIDDK)

Summary Information: Rectum

Rectum: The rectum is a hollow tube located in the lower abdomen and is a part of the large intestine and the digestive system and the gastrointestinal tract. The rectum is the last portion of large intestine through which feces are stored and pass before elimination through the anus. After digestion, peristalsis moves food residue from the small intestine into the large intestine, which absorbs water from the residue and forms feces.

Conditions that afflict the rectum include colorectal cancer, incontinence, and fecal impaction.
