B. It integrates glands, tear film, and neural pathways essential for tear homeostasis.

The lacrimal functional unit (lacrimal glands, ocular surface including cornea/conjunctiva/Meibomian glands, and their afferent/efferent neural connections) coordinates tear production, composition and reflexes. Dysfunction of this integrated unit underlies dry eye, so therapies aim to restore its function and tear homeostasis.
