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.
It is an important anatomical landmark in humans, and forms the boundary between the anal canal and the rectum according to the anatomic definition. [1] Colorectal surgeons instead define the anal canal as the zone from the anal verge to the anorectal ring (palpable structure formed by the external anal sphincter and the puborectalis muscle). [1]
In addition, the rectal route bypasses around two-thirds of the first-pass metabolism as the rectum's venous drainage is two-thirds systemic (middle and inferior rectal vein) and one-third hepatic portal system (superior rectal vein). This means the drug will reach the circulatory system with significantly less alteration and in greater ...
The rectal venous plexus consists of an external rectal plexus [4]: 598 [5]: 294 that is situated outside to the muscular wall, [3] [4]: 598 [5]: 294 and an internal rectal plexus [4]: 598 [5]: 294 that is situated in the submucosa [5]: 294 /deep to the mucosa [3] [4]: 598 of the rectum and proximal anal canal [3] at the anorectal junction.
The rectum (pl.: rectums or recta) is the final straight portion of the large intestine in humans and some other mammals, ... Blood supply and drainage.
The Macy Catheter is a specialized catheter designed to provide comfortable and discreet administration of ongoing medications via the rectal route. The catheter was developed to make rectal access more practical and provide a way to deliver and retain liquid formulations in the distal rectum so that health practitioners can leverage the established benefits of rectal administration.
The anal canal is the part that connects the rectum to the anus, located below the level of the pelvic diaphragm. [1] It is located within the anal triangle of the perineum, between the right and left ischioanal fossa. As the final functional segment of the bowel, it functions to regulate release of excrement by two muscular sphincter complexes ...
The anocutaneous line represents the transition point from non-keratinized stratified squamous epithelium of the anal canal to keratinized stratified squamous epithelium of the anus and perianal skin. [3] In live persons, the color of the line is white, hence the alternative name. It is named for John Hilton. [4]
