Question: 1 / 420

What is the primary function of the lacrimal gland?

To drain excess tears

To supply tears to the eye

The primary function of the lacrimal gland is to supply tears to the eye. The lacrimal gland produces and secretes the aqueous layer of the tear film, which helps to keep the surface of the eye moist, provides lubrication, and protects against infection. This tear film is essential for maintaining the health of the cornea and facilitating clear vision. The tears provided by the lacrimal gland also contain necessary nutrients and antibodies that contribute to the overall health and function of the eye.

While other options like draining excess tears or supporting the retina are related to eye health, they do not capture the primary role of the lacrimal gland itself, which is primarily concerned with tear production and secretion.
