Mainly secreted by salivary glands. There are many salivary glands in the human body. Small salivary glands are distributed in the mucosa of various parts of the oral cavity, including four kinds of glands: lip, cheek, tongue and palate, while large salivary glands are parotid gland, sublingual gland and submandibular gland. Parotid gland, submandibular gland and sublingual gland are the main salivary secretion organs, and the saliva secreted by salivary glands flows into the mouth through the catheter.

The benefits of saliva
1, keep it clean
The average saliva secretion per person per day can reach 1000- 1500ml. Food residues will accumulate in people's mouth, creating conditions for bacterial reproduction. The continuous flow of saliva in the mouth is equivalent to cleaning the teeth in time, thus keeping the mouth clean and healthy.
2. Tooth protection
Saliva can maintain the acid-base balance in the mouth, and the dissolution and deposition of enamel on the tooth surface is a dynamic process. Calcium ions, phosphate ions and fluoride ions in saliva play an important role in protecting enamel.
3, hemostasis and healing
Human saliva rich in histones can significantly shorten the healing time of wounds, and saliva can also help stop bleeding after oral trauma or tooth extraction. In the case of sudden injury and inconvenient cleaning, you can apply some saliva to the wound.
