Essay on Poop: Defecation and Abdominal Wall Muscles

Bowel movement (commonly known as No. 2, feces, defecation or bm) is the ultimate behavior of digestion and organisms are discharged from the gastrointestinal tract through the anus into solid waste, semisolid and / or liquid waste (Feces) is removed.

Humans excrete waste from several times a day to several times a week. The muscle contraction wave of the colon wall (called peristaltic movement) moves the rectum through the digestive tract by moving feces (called feces or feces). Undigested foods may also be excreted like this during digestion

The rectum enlarged part (anatomically as well: enormous part) functions as a facility to temporarily store unnecessary substances. Extension receptors from the nervous system located in the rectal wall stimulate the desire for bowel movement as the rectal wall expands with the filling material. The urge of this defecation arises from the reflex contraction of the rectum muscle, the relaxation of the internal sphincter of the anal, and the initial contraction of the skeletal muscle of the external anal sphincter. In the absence of any treatment, substances in the rectum are usually returned to the colon by reverse squering, where more water is absorbed, until the next large-scale peristaltic movement of the lateral and lower colons storage of feces . If the intestinal movement is delayed for a while, feces may become hard and cause constipation. Diarrhea may occur before excessive moisture is absorbed if the bowel movement is too early. [1]

When the rectum is full, as the pressure in the rectum rises, the wall of the anal canal separates and fecal material can enter the tube. When the material is pushed into the anal canal, the rectum becomes shorter and peristaltic waves push the stool out of the rectum. The internal anal sphincter and external anal sphincter, and the puborectalis muscle allow the feces to pull the anus through the muscle. [Required citation]

Defecation is normally assisted by trying to drain this air from a closed glottis with a deep breath (Valsalva action). This contraction of exhalation pectoral muscle, diaphragm muscle, abdominal wall muscle, and pelvic diaphragm muscle exerts pressure on the gastrointestinal tract. Ventilation at this time temporarily stops because the lung depresses the chest diaphragm and applies pressure. Rising blood pressure and reflex response in the chest

Simultaneously with defecation, it usually stimulates excretion of urine. Pectoral muscle, diaphragm, abdominal wall muscles, and pelvic diaphragm all apply pressure to the gastrointestinal tract. When the lung is pressed to push down the diaphragm, the breath temporarily stops. The blood pressure in the body rises and the blood pump capacity of the heart decreases. Defecation may be completely involuntary or spontaneous. Incontinence - loss of control of the evacuation process - progresses with age; it is also caused by surgery, obstetrics, spinal or other physical injuries, or by nerve injuries caused by diabetes, stroke or multiple sclerosis Sometimes. Bowel movements can also be affected by pain, fear, temperature rise, and mental or neurological complications. Diarrhea or abnormally frequent defecation is a characteristic symptom of many diseases and symptoms. It is most notable in diseases such as cholera and dysentery.

The abdominal muscle is an abdominal wall muscle which is continuous with the innermost chest of the pectoral muscle. It originates from the inner surfaces of the seventh to twelfth ribs, the thoracolumbar fascia and tendons. It is inserted along the white line of the oblique muscle and the tendon sheath. The fibers extend laterally inward. Potential outer abdominal slope and superficial abdomen are neurovascular surfaces. This neurovascular plane contains intercostal nerve, subcostal, subconjunctival and branching nerves, which is important to avoid damage in abdominal wall surgery.
