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.
The volatile compounds found in the anal-gland secretions were largely alcohols, aldehydes, and ketones. [21] Of the volatile compounds that were analyzed, the relative quantities of volatile compounds present in the test subjects’ anal sac secretions varied significantly between secretions collected outside and during mating season.

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.
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.
The anal verge refers to the distal end of the anal canal, a transitional zone between the epithelium of the anal canal and the perianal skin. It should not be confused with the pectinate line between the upper and lower zones within the anal canal. The anal gland secretes lymphal discharge and built-up fecal matter from the colon lining.
Castoreum. Castoreum / k æ s ˈ t ɔːr i ə m / is a yellowish exudate from the castor sacs of mature beavers used in combination with urine to scent mark their territory. [1] [2]Both beaver sexes have a pair of castor sacs and a pair of anal glands, located in two cavities under the skin between the pelvis and the base of the tail. [3]
And because of this location, "castoreum is often a combination of castor gland secretions, anal gland secretions, and urine." National Geographic describes it as a "musky, ...
Lesions which mechanically interfere with, or prevent the complete closure of the anal canal can cause a liquid stool or mucous rectal discharge. Such lesions include piles (inflamed hemorrhoids), anal fissures, anal cancer, or fistulae. Obstetric injury may tear the anal sphincters, and some of these injuries may be occult (undetected).
