How does poop come out of your body?

Answer 1

At the start of the cycle, the rectum ampulla acts as a temporary storage facility for the unneeded material. As additional fecal material enters the rectum, the rectal walls expand. A sufficient increase in fecal material in the rectum causes stretch receptors from the nervous system located in the rectal walls to trigger the contraction of rectal muscles, relaxation of the internal anal sphincter and an initial contraction of the skeletal muscle of the external sphincter. The relaxation of the internal anal sphincter causes a signal to be sent to the brain indicating an urge to defecate.

If this urge is not acted upon, the material in the rectum is often returned to the colon by reverse peristalsis where more water is absorbed, thus temporarily reducing pressure and stretching within the rectum. The additional fecal material is stored in the colon until the next mass 'peristaltic' movement of the transverse and descending colon. If defecation is delayed for a prolonged period the fecal matter may harden and autolyze, resulting in constipation.

Once the voluntary signal to defecate is sent back from the brain, the final phase of the cycle begins. The rectum now contracts and shortens in peristaltic waves, thus forcing fecal material out of the rectum and out through the anal canal. The internal and external anal sphincters along with the puborectalis muscle allow the feces to be passed by pulling the anus up over the exiting feces in shortening and contracting actions.

Answer 2

Well after you eat food it goes to your stomach then gos to your intestines. after the nutrients are sucked out of your food then it gos to your large intestine. there, it dries out and turns into poop. then it gos out your rectum (butt hole)(ass hole).

Answer 3

the digestive tract is made functional by the smooth muscle that lines its walls. these muscles contract to force material farther. several sphincters also aid the digestive process by pushing material through the tract. when your poop gets to the rectum, the muscles in that region push it out. so, to answer simply, muscles and gravity.

Answer 4

Because if you pull, you run the risk of it coming out of your mouth.

Answer 5

it comes out the nose actually better known as the nasal passage

Answer 6

food
