Even Though We are Not Usually Aware of the Process

Question

Even though we are not usually aware of the process, tears flow at all times from the _______.
A) sclera
B) cornea
C) conjunctiva
D) lacrimal duct

Accepted Answer

Tears are produced by the lacrimal gland and flow across the surface of the eye. Excess tears drain through the lacrimal duct, which empties into the nasal cavity. Therefore, tears flow from the lacrimal duct, not from the sclera, cornea, or conjunctiva.
