What is the primary function of salivary glands?

The primary function of salivary glands is to stimulate digestion. Salivary glands produce saliva, which contains enzymes such as amylase that begin the breakdown of carbohydrates in food. This enzymatic action is crucial for the digestive process, as it allows for better absorption of nutrients once the food passes into the stomach and intestines.

Saliva also serves other important functions, including lubricating food for easier swallowing and protecting oral tissues from microorganisms, but its role in initiating digestion is central to its purpose. By moistening the food and starting the chemical breakdown, salivary glands play an essential role in preparing food for further digestion, which is vital for overall gastrointestinal health.
