Mucous - Definition

January 2017


Definition


Mucous is a viscous substance that is often colorless and almost transparent. It is primarily produced by glandular cells in the body's various mucous membranes, those of soft tissue lining the body's organs and cavities. There are, therefore, different types of mucous, including nasal mucous produced from the nose, intestinal mucous, pulmonary mucous, and cervical mucous produced by the female genitalia. Secreted mucous creates an extremely effective protective barrier, which stops pathogens and irritants before they can reach and potentially damage the mucous membrane. Cystic fibrosis is a genetic disease characterized by abnormally viscous mucous that principally causes respiratory difficulties in the lungs and problems with the pancreas.
