Parotid Duct

The parotid duct, or parotid duct (ductus parotideus), is one of the ducts that form the parotid gland. It starts from the base of the parotid salivary gland and passes through its body, then connects with the sublingual salivary gland, forming the Stenon's duct.

The parotid gland is one of the largest salivary glands in the human body and is located on the face. It consists of many small lobules, each of which has its own duct. The parotid duct is one such duct and has an important function in salivation.

The parotid duct has a length of about 3-5 cm and a diameter of about 2-4 mm. It passes through the body of the parotid gland and ends at the base of the tongue. Inside the duct is the secretion of the parotid gland - saliva.

Saliva contains many important substances, such as enzymes that help break down food, and minerals such as calcium and phosphorus, which are essential for healthy teeth and bones. In addition, saliva has antibacterial properties and protects the oral cavity from infections.

One of the main functions of the parotid duct is the secretion of saliva. During the chewing process, food is crushed and mixed with saliva, which makes it easier to digest and absorb. The parotid duct is also involved in maintaining oral moisture and protecting teeth from caries.

However, the parotid duct can be damaged by facial trauma or other diseases. For example, if the parotid gland becomes inflamed (mumps) or if a cyst forms in the area of ​​the parotid gland, the duct may be blocked and will not be able to perform its function.

Overall, the parotid duct plays an important role in the functioning of the parotid gland and salivation, and also protects the oral cavity from infection and damage.



On average, the parotid gland begins to work with the onset of puberty and the duration of its functioning does not exceed twenty-five years. The ducts of the parotid glands are most often spontaneous and located caudally, when all the ducts of the parotid sac pass from or near the organ, communicating with the perivascular fluid. The main part of the ducts of the parotid salivary glands opens independently into the oral cavity with the help of the parotid duct.
