There are three main types of salivary glands in the human body:
1. Parotid glands: These are the largest of the salivary glands and are located in front of the ears, just below the skin. They produce a watery type of saliva that is rich in enzymes and helps to break down carbohydrates in food.
2. Submandibular glands: These glands are located beneath the lower jaw and produce a mixture of watery and mucous saliva. This type of saliva helps to lubricate the mouth and aid in swallowing.
3. Sublingual glands: These are the smallest of the salivary glands and are located beneath the tongue. They produce a thick, mucous saliva that helps to keep the mouth moist and protect the oral tissues.
Each type of salivary gland plays a unique role in the production of saliva and helps to maintain oral health and function.

Major Salivary Glands
- Parotid glands: Located on either side of the face, just below the ears. They produce a watery, protein-rich saliva. - Submandibular glands: Located below the mandible (lower jawbone). They produce a thick, viscous saliva that is rich in mucin (a glycoprotein). - Sublingual glands: Located under the tongue. They produce a thin, watery saliva that is rich in amylase (an enzyme that helps digest carbohydrates).
Minor Salivary Glands
- Labial glands: Located in the lips. - Buccal glands: Located in the cheeks. - Palatal glands: Located in the palate (roof of the mouth). - Lingual glands: Located in the tongue.
Types of Saliva
The different types of salivary glands produce different types of saliva, which vary in composition and function:
- Serous saliva: Produced by the parotid glands, it is watery and contains proteins such as amylase and lysozyme. - Mucous saliva: Produced by the submandibular and sublingual glands, it is thick and viscous and contains mucin. - Mixed saliva: A combination of serous and mucous saliva, produced by all three major salivary glands.
