the segment of the large intestine that travels downward on the left side of the abdomen
The descending colon is a portion of the large intestine located on the left side of the abdomen, extending from the splenic flexure to the sigmoid colon. Its main function is to receive the undigested material from the transverse colon and further facilitate the absorption of water and electrolytes while compacting the waste into feces.
