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 lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
Digestion: Saliva contains amylase, which hydrolyses starch into glucose, maltose, and dextrin. As a result, saliva allows some digestion to occur before the food reaches the stomach. [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 ...

Saliva is an important component of the taste mechanism. Saliva both interacts with and protects the taste receptors in the mouth. [5] Saliva mediates sour and sweet tastes through bicarbonate ions and glutamate, respectively. [6] The salt taste is induced when sodium chloride levels surpass the concentration in the saliva. [6]
Because saliva is stimulated to flow more with the thought, sight or smell of food, or with chewing, pain and swelling will often get suddenly worse just before and during a meal ("peri-prandial"), and then slowly decrease after eating, this is termed meal time syndrome. However, calculi are not the only reasons that a salivary gland may become ...
“I don’t think it’s necessarily a bad sign,” Ramakrishnan says, just odorants reaching the olfactory nerve that wouldn’t have otherwise. As a result, “you smell stuff you don’t ...
The odor occurs from the smell of ammonia, which is created in the saliva as a breakdown product of urea. [2] Uremic fetor is usually associated with an unpleasant metallic taste and can be a symptom of chronic kidney disease. People with uremia can also develop anorexia, abdominal pain, nausea, vomiting, and gastrointestinal bleeding.
