Mucins have been found to have important functions in defense against bacterial and fungal infections. MUC5B, the predominant mucin in the mouth and female genital tract, has been shown to significantly reduce attachment and biofilm formation of Streptococcus mutans, a bacterium with the potential to form cavities.

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 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 lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
Artificial saliva for dry mouth in a mouthwash form. Artificial saliva or salivary substitutes refer to a synthetically produced liquid that mimics the natural secretion of saliva. It is designed as a symptomatic relief for xerostomia, a condition characterised by dryness in the mouth and is available over-the-counter.
The mouth is the only place in the body which provides the sensation of taste. Due to these unique physiological features, the oral mucosa must fulfil a number of distinct functions. Protection: One of the main functions of the oral mucosa is to physically protect the underlying tissues from the mechanical forces, microbes and toxins in the ...

The function of the salivary glands is to secrete saliva, which has a lubricating function, which protects the mucosa of the mouth during eating and speaking. [2] Saliva also contains digestive enzymes (e.g. salivary amylase), has antimicrobial action, and acts as a buffer. [3]
They produce a glycoprotein, mucin that absorbs water to form a sticky secretion called mucus. They are from 12 to 25 mm. long, and about 8 mm. broad, and each opens by three or four ducts on the under surface of the apex. The Weber's glands are an example of muciparous glands located along the tongue.
