At the end of the large intestine, which structure stores waste material as a solid before elimination?

The end of the large intestine stores waste in the rectum. As water absorption finishes along the colon, the stool becomes solid and is held in the rectal ampulla, a temporary reservoir that signals the body when it’s ready to defecate. The rectum’s stretch receptors trigger the defecation reflex and coordinate with the anal sphincters to control elimination. The anus is just the exit opening, not a storage site. The cecum is the starting pouch of the large intestine, and the sigmoid colon mainly moves and stores stool before it reaches the rectum, but the actual storage before elimination occurs in the rectum.
