What is salivary gland?


The salivary glands are an example of exocrine glands that produce saliva through a system of ducts and empty it into our mouth through.

They keep the mouth and other parts of the digestive system moist, prevent infections from developing in your mouth or throat, and help in swallowing-chewing also.

Saliva is composed of a variety of electrolytes, including sodium, potassium, calcium, magnesium, bicarbonate, and phosphates.

Proteins, enzymes, mucins, and nitrogenous products, such as urea and ammonia, are also found in the saliva.

There are two types of salivary glands:

1. Major salivary glands-  Humans have three pair of major salivary glands (parotid, submandibular, and sublingual). They’re located on each side of our face.

2. Minor salivary glands-  Humans have hundreds of minor salivary glands, which are too small to be seen without a microscope. Most of them are found in the lining of the lips, the roof of the mouth, and the tongue, as well as inside the cheeks, sinuses, nose, and larynx.
