What Is Spit?
Salty liquid is produced by salivary glands, usually in the mouth region. It helps lubricate your throat for swallowing and keeps good bacteria around. There's definitely wetners all over the body, but these specific ones for saliva are mostly water.
You need to clean a smudge of your glasses? Use some spit! Gotta make some food moist so you can swallow it? Why not try spit? Lips too dry to whistle a tune? My friend, spit is the bodily excretion for you! Spit: don't leave home without it!
