Question: Why do you poop!?
Why do people poop!? What would happen if we didn't!?Www@Answer-Health@Com


Answers:
Fecal matter builts up in your sigmoid colon!. When there is enough pressure, you feel the urge to get it out by pooping, and in most cases, you do!.

If you dont poop, something in your large intestine called, villai, will absorb all the water in your poop, which is fine, but eventually, the poop runs out of water, and you start reabsorbing the things your body was trying to get rid of in the first place!. (At this point, it would be hard to poop if you tried)
Then, after enough fecal matter is absorbed, you get sepsis!. (Poopy infection) then septic shock, then death!.

Go poop when you have to!. If you can't, eat prunes, if you still can't, go to a doctor!.

I hope I've helped,

What the guy above me is saying is that if you didn't poop, then there would be no way for the food you way to exit your body, and would probably cause some sort of backup!. Which sounds painful!. I suggest that they take some laxitives in that case!.Www@Answer-Health@Com

you poop because all the waste in your body has to come out some way like pee when you drink you can't store all that drunken stuff inside your stomachWww@Answer-Health@Com

Defacation is the act or process by which organisms eliminate solid, semisolid or liquid waste material (feces) from the digestive tract via the anus!. Humans expel feces with a frequency varying from a few times daily to a few times weekly; sloths can go a week without expelling!. Waves of muscular contraction known as peristalsis in the walls of the colon move fecal matter through the digestive tract towards the rectum!. Undigested food may also be expelled this way; this process is called egestion!.

The rectum ampulla (anatomically also: ampulla recti) acts as a temporary storage facility for the unneeded material!. As the rectal walls expand due to the material filling it, stretch receptors from the nervous system located in the rectal walls stimulate the desire to defecate!. This urge to defecate arises from the reflex contraction of rectal muscles, relaxation of the internal anal sphincter and an initial contraction of the skeletal muscle of the external sphincter!. If the urge is not acted upon, the material in the rectum is often returned to the colon by reverse peristalsis where more water is absorbed and the faeces is stored 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, resulting in constipation!.

When the rectum is full, an increase in intra-rectal pressure forces the walls of the anal canal apart allowing the fecal matter to enter the canal!. The rectum shortens as material is forced into the anal canal and peristaltic waves push the feces out of the rectum!. The internal and external anal sphincters along with the puborectalis muscle, allow the feces to be passed by muscles pulling the anus up over the exiting feces!.

Defecation is normally assisted by taking a deep breath and trying to expel this air against a closed glottis (Valsalva maneuver)!. This contraction of expiratory chest muscles, diaphragm, abdominal wall muscles, and pelvic diaphragm exert pressure on the digestive tract!. ventilation at this point temporarily ceases as the lungs push the chest diaphragm down in order to exert the pressure!. Thoracic Blood pressure rises and as a reflex response the amount of blood pumped by the heart decreases!. Death has been known to occur in cases where defecation causes the blood pressure to rise enough to cause the rupture of an aneurysm or to dislodge blood clots (see thrombosis)!. Also, in release of the Valsalva maneuver blood pressure falls, this coupled often with standing up quickly to leave the toilet results in a common incidence of blackouts in this situation!.

When defecating, the external sphincter muscles relax!. The anal and urethal sphincter muscles are closely linked, and experiments by Dr!. Harrison Weed at the Ohio State University Medical Center have shown that they can only be contracted together, not individually, and that they both show relaxation during urination[citation needed]!. This explains why defecation is frequently accompanied with urination!.

Defecation may be involuntary or under voluntary control!. Young children learn voluntary control through the process of toilet training!. Once trained, loss of control causing fecal incontinence may be caused by physical injury (such as damage to the anal sphincter that may result from an episiotomy), intense fright, inflammatory bowel disease, impaired water absorption in the colon (see diarrhea), and psychological or neurological factors!.

The positions and modalities of defecation are culture-dependent!. In some regions of the world, such as South Asia, East Asia and rural parts of the Middle East, it is customary to squat (typically using squat toilets), while in most of the Western World sit-down toilets are used!.

The anus and buttocks may be cleansed with toilet paper, similar paper products, or other absorbent material!. In some cultures water is used (e!.g!. as with a bidet) either in addition or exclusively!. In Japan, some toilets known as washlets are designed to wash and dry the anus of the user after defecation (see anal cleansing)!.Www@Answer-Health@Com
