Expert Solution

Step 1: Role of mucus in respiratory system

The mucus in the respiratory system fills in as a pivotal guard component to safeguard the lungs and aviation routes. It is created by specific challis cells and other secretory cells covering the respiratory lot.

The essential job of mucus is to trap unfamiliar particles, like residue, microscopic organisms, and different microorganisms, as well as breathe in aggravations like dust and smoke.

When these particles are caught in the tacky bodily fluid, little hair-like designs called cilia on the outer layer of respiratory epithelial cells work in facilitated, wave-like movements to move the bodily fluid vertically and out of the aviation routes.
