The structure that collects tears before drainage into the nasolacrimal duct?

• A. Lacrimal Sac
• B. Lacrimal Ducts
• C. Lacrimal Fluid
• D. Extraocular

Answer: (A)

Tear drainage uses a collecting reservoir called the lacrimal sac. Tears produced by the lacrimal gland wash over the eye and drain through tiny openings into the canaliculi, then into the lacrimal sac. The sac holds the tears before they pass down the nasolacrimal duct into the nasal cavity. The ducts (canaliculi) are the channels that carry tears to the sac, not the place where tears are gathered. Lacrimal fluid is simply the tear liquid itself, and extraocular refers to the eye muscles that move the eye, not tear collection.
