The colon, also known as the large intestine, is the last part of the digestive system. It is much wider than the small intestine, and is also much shorter (approximately 1.8m in length).
The colon is divided into four parts: ascending (on the right side of the body), transverse (across the body), descending (on left side of the body), and the sigmoid colon (leading into the rectum).
Answer and Explanation:
The answer to the question is (b): the primary function of the colon is to reduce the volume of the chyme.
The cells of the colon are able to absorb both water and salt. Absorption of water reduces the volume of the waste material.
No actual digestion occurs in the colon, unlike in the small intestine.
