What Structure Drains Tears into the Nasal Cavity

Question

What structure drains tears into the nasal cavity?
A) lacrimal puncta
B) nasolacrimal duct
C) lacrimal ducts
D) lacrimal canals

Accepted Answer

The nasolacrimal duct drains tears into the nasal cavity. The lacrimal puncta are small openings on the edge of each eyelid that allow tears to enter the lacrimal canals, which then drain into the nasolacrimal duct. The lacrimal ducts do not exist, so choice C is incorrect. Similarly, lacrimal canals do exist but do not directly drain tears into the nasal cavity, so choice D is also incorrect.
