Explanation: 

Detailed explanation-1: -The transverse colon continues as the descending colon. The two are demarcated at the splenic flexure. The descending colon is a retroperitoneal organ and related to paracolic gutters on either side. It terminates into the sigmoid colon, which is the fifth part of the large intestine.

Detailed explanation-2: -The sigmoid colon is the last section of the bowel-the part that attaches to the rectum. It pushes feces along the bowel tract. It’s about a foot and a half long (around 40 centimeters) and is shaped like the letter “s.” Its job is to hold feces until you’re ready to go to the bathroom.
