Frequently Asked Questions
What is the colon and what does it do?
The gastrointestinal (GI) tract has several structures starting
with the mouth, followed by the esophagus, stomach, intestines,
and ending with the rectum.
The intestines have two parts: the small intestine and large intestine
(the colon). The colon is the end section of the intestine, and
is six to twelve feet in length. It begins on the right lower area
of the abdomen, goes up along the right side, across the top of
the abdomen, down the left side and ends at the anus. The last six
inches of the colon is the rectum.
The primary function of the colon is water absorption. Very little
nutrition absorption takes place in the colon. As a result, we can
remove a portion or the entire colon and your body can continue
to have good nutrition.
What is the rectum and what does it do?
The rectum is the last six inches of the large intestine or colon.
It serves as a reservoir or holding tank for the stool before a
bowel movement occurs.
