PATHOLOGY

Detailed explanation-1: -Tears are created in lacrimal glands in the upper outside corners of your eyes. They’re mostly salt and water. This fluid moves across your eyes as you blink and is mixed with oil from your meibomian glands to form your tears.

Detailed explanation-2: -Foreign bodies that enter the eye are washed out by tears. Moreover, tears contain a substance called lysozyme, which has an antibacterial action, and works to prevent invasion and infection by microbes.

Detailed explanation-3: -Among the nonspecific chemical defenses of the body are the secretions of lubricating glands. The tears and saliva contain the enzyme lysozyme, which breaks down the peptidoglycan of the cell wall of Gram-positive bacteria.

Detailed explanation-4: -Basal Tears. Containing three separate layers, basal tears are complex. Emotional Tears. Your eyes produce emotional tears when you’re overcome with emotion. Reflex Tears. The eye’s lacrimal gland produces reflex tears, which are composed primarily of water. 05-Oct-2022
