Which Organ Produces Saliva?
The salivary glands produce saliva. These glands are small organs with a significant role in digestion and oral health.
Humans possess three pairs of major salivary glands:
- Parotid glands: These are the largest salivary glands.
- Submandibular glands: These glands are located beneath the jaw.
- Sublingual glands: These are the smallest of the major salivary glands, situated under the tongue.
In addition to these major glands, numerous smaller minor salivary glands are distributed throughout the mouth and oral cavity. All these glands contribute to the overall saliva production.
The structure of these glands involves a system of ducts that lead to secretory acini (end pieces), responsible for saliva secretion. Saliva itself is a complex fluid containing water, electrolytes, enzymes (like amylase), and other proteins. Its functions include lubricating food for easier swallowing, initiating carbohydrate digestion, and protecting teeth and oral tissues.
Saliva production is a complex process, stimulated even by the anticipation of food. The glands' activity is controlled by both the nervous system (responding to stimuli like smell and taste) and the endocrine system.
