What is the overview and what influences it?

When a person is first born, the defecation reflex occurs unconsciously. As you grow older and become more potty trained, learn to control The urge to poop.

The defecation reflex begins in the colon. The muscles in the colon wall help move stool into the rectum through a process called peristalsis.

When stool fills the rectum, the walls stretch and receptors are activated. This signals the brain that it’s time to defecate. The body passes a small amount of stool into the anal canal, and this helps determine whether stool or gas needs to be expelled.

At this time, a person can voluntarily control the anal sphincter. You can either relax and defecate or hold your stool until an appropriate time. If a toilet break is improperly timed, the walls of the rectum relax and the defecation reflex temporarily disappears.

When a person goes to the toilet, they use their abdominal muscles to push down on the stool, increasing the pressure. At the same time, relax the external anal sphincter.

This coordinated movement helps expel stool from the body.
