The mouth’s salivary glands produce between 1 to 2 liters of saliva a day. Without this, it would be difficult to swallow food as well as identify flavors.
This fluid consists of 95% water. In addition, it has components such as phosphate, bicarbonate, calcium, lysozyme and different enzymes that allow it to perform a wide range of functions.
According to the Organization of Ibero-American States for Education, Science and Culture, saliva is an efficient diagnostic method for detecting diseases such as diabetes, the presence of oncogenes, cystic fibrosis and AIDS viral antibodies. The organization also states that saliva helps to heal wounds.
A study from the National Institute of Dental and Craniofacial Research (United States) emphasizes how predictive it is: “Because of the hormones it contains and because of the other chemical substances that it holds, you can tell whether someone smokes, is stressed-out or, with women, when they will ovulate.” Learn more about how saliva works.
- Regulates temperature: The water in saliva absorbs the body’s heat, refreshing the body
- Taste: Saliva is in charge of dissolving the chemical compounds that are released from food when it is chewed. The tongue’s taste buds are then stimulated which then send the sensation of the taste to the brain.
