Quick Summary

Stensen's duct, also known as the duct of Steno, is the duct of the parotid gland. This duct opens on the inner surface of the cheek, opposite the second upper molar tooth. The parotid glands are the largest of the three major salivary glands in humans and are located between the ear and the ascending branch of the lower jaw. These glands secrete mainly serous fluids, which are a more liquid, opalescent fluid composed of water and proteins like the digestive enzyme amylase. Saliva plays a crucial role in moistening and softening food in the mouth.123
