saliva

The watery fluid that is secreted into the mouth by the salivary glands. In many animals, including humans, it contains the enzyme amylase, which breaks down carbohydrates. Saliva also contains mucus, which lubricates food for swallowing, and various proteins and mineral salts. Some special chemicals occur in the saliva of other animals, such as anticoagulants in the saliva of mosquitoes.
