Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lingual lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
It has also been defined as increased amount of saliva in the mouth, which may also be caused by decreased clearance of saliva. [4] Hypersalivation can contribute to drooling if there is an inability to keep the mouth closed or difficulty in swallowing (dysphagia) the excess saliva, which can lead to excessive spitting.

[30] Taste: [31] Saliva acts as a solvent in which solid particles can dissolve and enter the taste buds through oral mucosa located on the tongue. These taste ...
Salivary gland dysfunction affects the flow, amount, or quality of saliva produced. A reduced salivation is termed hyposalivation.Hyposalivation often results in a dry mouth condition called xerostomia, and this can cause tooth decay due to the loss of the protective properties of saliva.
Normal mucus often looks clear or white for most people, experts say. But mucus changes color, depending on the individual’s environment, in response to various germs and more, he adds.
