The tear drainage system includes the sac and ducts.

• A. Lacrimal Apparatus
• B. Lacrimal Fluid
• C. Conjunctiva
• D. Extraocular

Answer: (A)

Tear drainage is handled by the lacrimal apparatus, the structures that carry tears away from the eye into the nasal cavity. The drainage portion includes the lacrimal sac and the ducts that lead to the nasal cavity. This makes the lacrimal apparatus the right term for the system described, since it specifically covers the pathways involved in draining tears. The other options refer to different things: lacrimal fluid is the tears themselves, conjunctiva is the mucous membrane lining the eyelids and eyeball, and extraocular relates to the muscles that move the eye.
