Which gland produces fluid that keeps the conjunctiva moist?

• A. Optic chiasma.
• B. Posterior orbit.
• C. Corneal duct.
• D. Lacrimal gland.

Answer: (D)

The lacrimal gland is responsible for producing tears, which play a crucial role in keeping the conjunctiva moist. The conjunctiva is the transparent membrane covering the white part of the eye and the inner surface of the eyelids. This moisture is essential for maintaining eye health, providing lubrication, washing away foreign particles, and preventing dryness. The tears produced by the lacrimal gland also contain enzymes and antibodies that help to protect the eye from infection. Other choices, such as the optic chiasma, posterior orbit, and corneal duct, do not have a role in tear production or maintaining moisture for the conjunctiva. The optic chiasma is involved in vision processing, the posterior orbit refers to the area behind the eye, and the corneal duct is related to tear drainage rather than production. This highlights the specific function of the lacrimal gland in maintaining adequate moisture levels for the conjunctiva and the overall health of the eye.
