What does descending colon and the rectum mean?

Descending Colon:

- Part of the large intestine located on the left side of the abdomen.

- It connects the transverse colon to the sigmoid colon.

- The primary function of the descending colon is to absorb water and electrolytes from the stool, further solidifying it.

- It also stores stool temporarily until it moves to the sigmoid colon for elimination.

Rectum:

- The final segment of the large intestine, connecting the sigmoid colon to the anus.

- The rectum is responsible for storing stool and facilitating its controlled elimination through the process of defecation.

- It has specialised muscles and sphincters that allow for the retention and release of stool.

- The rectum also has sensory receptors that help detect the need for defecation.
