WHERE MUCUS COMES FROM

. Posted in HEALTHY BODY

The cavities of the sinuses are lined with mucous membranes, or tissues, that look like the inside of your mouth. These membranes are smooth and shiny and made up of various distinct types of cells. First, a layer of goblet cells produce the mucus through tiny tubes, forming the mucous blanket. These goblet cells are interspersed between hair-like cells called ciliated columnar cells, which move the mucus across the surface of the membrane (6). The membranes of all the sinuses are covered

with these ciliated columnar cells. Together, the mucous membranes, the ciliated columnar cells, and the mucus itself all protect the body by establishing a defense system in the upper airway, or the nose and the sinuses.

A base layer below the goblet cells and the ciliated columnar cells is formed by basal cells. These cells form the barrier preventing infection and toxins from entering the body through the sinuses. The basal lining is a defense shield for the body in the same way that your skin protects your insides from foreign substances.
