An Important Component of the Lamina Propria in the Upper

Question

An important component of the lamina propria in the upper respiratory system is
A) sweat glands.
B) ceruminous glands.
C) mucus glands.
D) serous glands.
E) smooth muscle cells.

Accepted Answer

The lamina propria in the upper respiratory system contains mucus glands, which secrete mucus to help trap and remove foreign particles from the airways. This is an important component of the body's defense against respiratory infections. Sweat, ceruminous, and serous glands are not typically found in the lamina propria of the upper respiratory system. Smooth muscle cells may be present in the lamina propria, but they are not the most important component for respiratory defense.
