GENERAL HISTOLOGY

Detailed explanation-1: -Peristalsis helps move the stool into your rectum. Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement. Watch this video to see how food moves through your GI tract link.

Detailed explanation-2: -The rectum is where feces are stored until they leave the digestive system through the anus as a bowel movement.

Detailed explanation-3: -The rectum receives stool from the colon, sends signals to the brain if there is stool to be evacuated, and holds stool until evacuation can happen. Anus: The last part of the digestive tract, the anus, consists of pelvic floor muscles and two anal sphincters (internal and external).

Detailed explanation-4: -The colon’s job is to dehydrate what’s left of the food and form it into stool. It does this by slowly absorbing water and electrolytes as its muscle system moves the waste along.

Detailed explanation-5: -Muscles in the wall of your colon separate the waste into small segments that are pushed into your lower colon and rectum. As the rectal walls are stretched, they signal the need for a bowel movement. When the sphincter muscles in your anus relax, the rectal walls contract to increase pressure.
