Defecation is the final act of digestion, by which organisms eliminate solid, semisolid, or liquid waste material from the digestive tract via the anus.
Rectal prolapse is when the rectal walls have prolapsed to a degree where they protrude out the anus and are visible outside the body. However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on if the prolapsed section is visible externally, and if the full or only partial thickness of the rectal wall is involved.
Shigella dysenteriae is a species of the rod-shaped bacterial genus Shigella. Shigella species can cause shigellosis. Shigellae are Gram-negative, non-spore-forming, facultatively anaerobic, nonmotile bacteria.
Proctitis is an inflammation of the anus and the lining of the rectum, affecting only the last 6 inches of the rectum.
A varix is an abnormally dilated vessel with a tortuous course. Varices usually occur in the venous system, but may also occur in arterial or lymphatic vessels.
Aminophenazone is a pyrazolone with analgesic, anti-inflammatory, and antipyretic properties but has risk of agranulocytosis. A breath test with 13C-labeled aminopyrine has been used as a non-invasive measure of cytochrome P-450 metabolic activity in liver function tests. It is also used in measuring the total body water in the human body system. Production and use have been banned in France, Thailand and India.
The middle rectal artery is an artery in the pelvis that supplies blood to the rectum.
The inferior vesical artery or inferior vesicle artery is an artery in the pelvis that supplies the lower part of the bladder.
The rectal venous plexus surrounds the rectum, and communicates in front with the vesical venous plexus in the male, and the vaginal venous plexus in the female.
The internal iliac vein begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to form the common iliac vein.
The inferior hypogastric plexus is a plexus of nerves that supplies the viscera of the pelvic cavity. The inferior hypogastric plexus gives rise to the prostatic plexus in males and the uterovaginal plexus in females.
The vaginal venous plexuses are placed at the sides of the vagina; they communicate with the uterine venous plexuses, vesical venous plexus, and rectal venous plexuses, and are drained by the vaginal veins, one on either side, into the hypogastric veins.
A venous plexus is a congregation of multiple veins.
Vesical refers to the urinary bladder and its relevant and nearby structures and functions, including:
Rectal discharge is intermittent or continuous expression of liquid from the anus. Normal rectal mucus is needed for proper excretion of waste. Otherwise, this is closely related to types of fecal incontinence but the term rectal discharge does not necessarily imply degrees of incontinence. Types of fecal incontinence that produce a liquid leakage could be thought of as a type of rectal discharge.
Obstructed defecation, is "difficulty in evacuation or emptying the rectum [which] may occur even with frequent visits to the toilet and even with passing soft motions". The conditions that can create the symptom are sometimes grouped together as defecation disorders. The symptom tenesmus is a closely related topic. Another source defines evacuatory dysfunction as "a constellation of symptoms such as prolonged repeated straining at bowel movements, sensation of incomplete evacuation, and the need for digital manipulation".
