What is tears : spit or sweat?

Answer 1

neither..idkk

Answer 2

Tears are the salty fluid that lubricates and helps protect the cornea, the membrane that covers the front of the eye.

Normal tears that cover the corneal surface comprise three layers:

the lipid, or oil layer, which is the outer layer of the tear film and helps prevent the lacrimal layer beneath it from evaporating or overflowing the lower eyelid

the lacrimal, or watery layer, which is the middle layer and contains salts, proteins, and an enzyme called lysozyme that actually protect and nourish the eye

the mucoid, or mucus layer, which is the bottom layer of tears. It contains cells called goblet cells that cause the tears to adhere to the eye.

All three layers of tears are necessary for proper lubrication.

Hope this answers your question.
