PATHOLOGY

Detailed explanation-1: -The mucus serves as a first line of innate defense and is produced by surface goblet cells, other epithelial cells, and glands that are all intimately coupled to other parts of the innate and adaptive immune systems. The mucus is composed of many different molecules with mucins forming the basic skeleton.

Detailed explanation-2: -The innate immune system is the body’s first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the “nonspecific” immune system.

Detailed explanation-3: -The mucosa functions primarily as part of your body’s immune system. It provides a barrier against foreign particles, captures them in its sticky mucus and clears them out. Immune cells and natural antibiotics in the mucus defend against pathogens, while the lubrication defends against injury.

Detailed explanation-4: -Cough reflex. Enzymes in tears and skin oils. Mucus, which traps bacteria and small particles. Skin. Stomach acid. 23-Jan-2022
