The salivary glands are specialized organs in the mouth that produce saliva, a fluid essential for digestion and oral health. There are three main pairs of salivary glands: the parotid glands, located near the ears; the submandibular glands, found beneath the jaw; and the sublingual glands, situated under the tongue. Saliva helps break down food, keeps the mouth moist, and protects teeth from decay. Saliva contains enzymes, electrolytes, and antimicrobial agents that aid in digestion and maintain oral hygiene. When food enters the mouth, the salivary glands are stimulated to release saliva, which begins the process of breaking down carbohydrates and lubricating food for easier swallowing.
