What are salivary glands?
All mammals have salivary glands, and so do humans.
Salivary glands are usually found in the root and body of the tongue. Salivary glands produce saliva, which is also called spit.
Saliva is moisture in the mouth. It helps an animal to swallow its food.
A lot of saliva that drips from an animal’s mouth is often called slobber, dribble, drool, or slaver.
