Question

what are the components of saliva

Answer 1

Saliva is a watery substance formed in the mouths of animals, secreted by the salivary glands. Human saliva comprises 99.5⁠% waterplus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as amylase and lipase), antimicrobial agents such as secretory IgA and lysozyme.[1] The enzymes found in saliva are essential in beginning the process of digestion of dietary starches and fats. These enzymes also play a role in breaking down food particles entrapped within dental crevices, thus protecting teeth from bacterial decay.[2] Furthermore, saliva serves a lubricative function, wetting food and permitting the initiation of swallowing, and protecting the mucosal surfaces of the oral cavity from desiccation.[3]

Various animal species have special uses for saliva that go beyond predigestion. Some swifts use their gummy saliva to build nests. Aerodramus nests form the basis of bird's nest soup.[4] Cobras, vipers, and certain other members of the venom clade hunt with venomous saliva injected by fangs. Some caterpillars, produce silk fiber from salivary glands.[citation needed]
