The secretion of anal gland content contains mucin, that is rich in sialic acid and other anti-microbial proteins, like lysozyme, immunoglobulin A, and lactoferrin. [14] There is also an abundance of gram-positive cocci since they are part of the anal glands normal flora. [ 14 ]
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 (e.g., fecal leakage) but the term rectal discharge does not necessarily imply degrees of incontinence.
Surgery involving the rectum (e.g. lower anterior resection, often performed for colorectal cancer), radiotherapy directed at the rectum, and inflammatory bowel disease can cause scarring, which may result in the walls of the rectum becoming stiff and inelastic, reducing compliance. Reduced rectal storage capacity may lead to urge incontinence ...
The human rectum is a part of the lower gastrointestinal tract. The rectum is a continuation of the sigmoid colon, and connects to the anus. The rectum follows the shape of the sacrum and ends in an expanded section called an ampulla where feces is stored before its release via the anal canal.
Magnesium-containing agents also cause the release of cholecystokinin, which increases intestinal motility and fluid secretion. [3] Saline laxatives may alter a patient's fluid and electrolyte balance. Properties. Site of action: small and large intestines; Onset of action: 0.5–3 hours (oral), 2–15 minutes (rectal)
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus.The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines.
In humans, the anus (pl.: anuses or ani; from Latin ānus, "ring", "circle") [1] [2] is the external opening of the rectum located inside the intergluteal cleft.Two sphincters control the exit of feces from the body during an act of defecation, which is the primary function of the anus.
It is about 5 mm thick, and is formed by an aggregation of the smooth (involuntary) circular muscle fibers of the rectum. [citation needed] The internal anal sphincter aids the sphincter ani externus to occlude the anal aperture and aids in the expulsion of the feces. Its action is entirely involuntary. It is normally in a state of continuous ...
