Where are lacrimal glands located, and what is their function?

Lacrimal glands are located in the upper-outer aspect of each eye. Their primary function is to produce tears, which serve to moisten the surface of the eye, providing lubrication. This moisture helps to prevent dryness and irritation, ensuring the smooth movement of the eyelids over the eye's surface. Additionally, the tears created by the lacrimal glands contain enzymes that have antibacterial properties, helping to protect against infections. The drainage aspect of these glands also plays a significant role in maintaining proper tear balance and preventing overflow, as tears can drain through the lacrimal ducts into the nasal cavity. This anatomical positioning and function are vital for the overall health and comfort of the eyes.
