The lacrimal glands are the glands that produce tears.
Lacrimal Gland Function
These glands, located behind the upper outside corner of your eyes, are responsible for creating the watery part of your tears. Each lacrimal gland is roughly the size of an almond. They secrete a salty fluid that helps keep your eyes moist and free from irritants.
The tears produced by the lacrimal glands serve several important functions:
- Lubrication: They keep the eyes moist, preventing dryness and discomfort.
- Protection: Tears help to wash away dust, debris, and other irritants from the surface of the eye.
- Nourishment: Tears provide nutrients to the cornea, the clear outer layer of the eye.
- Infection prevention: Tears contain antibodies and enzymes that help fight against infection.
Anatomy of the Lacrimal Apparatus
The lacrimal apparatus includes:
- Lacrimal glands: Produce the tears.
- Lacrimal ducts: Tiny tubes that carry tears from the lacrimal glands to the eye's surface.
- Puncta: Small openings in the inner corners of the eyelids where tears drain into.
- Lacrimal sac: A small pouch in the inner corner of the eye where tears collect.
- Nasolacrimal duct: The tube that carries tears from the lacrimal sac to the nasal cavity. This is why your nose runs when you cry.
The entire tear system works together to produce, distribute, and drain tears effectively, maintaining the health of your eyes.
