Mucus

Description

mucus

A slippery secretion by the mucus membranes and glands. Mucus is also found in the digestive, reproductive, respiratory, gastrointestinal, and urogenital tracts. A layer of mucus along the inner walls of the stomach is vital to protect the cell linings of that organ from the highly acidic environment within it. The same protective layer of mucus is what comes out when you sneeze. Mucus does not digest in the intestinal tract, so mucus commonly appears in fecal matter whether its origin is from the intestines, or swallowed.

Function

Helps clear debris in nasal passages and moistens the linings. It contains an antiseptic that serves to protect cells in the respiratory, gastrointestinal, reproductive, and urogenital tracts, as well as in the visual and auditory systems in mammals.

In the nasal cavity as well as in the digestive, reproductive, respiratory, gastrointestinal, and urogenital tracts.
