What does the lacrimal sac produce?
Tears
Which structure is also known as the tear sac?
lacrimal canal no no it's lacrimal sac
What would you find located in the lacrimal fossa?
The lacrimal gland, which produces tears, is located in the lacrimal fossa. It is situated in the upper outer portion of the orbit of the eye.
Which structure is on the medial aspect of each eye and drains tears into the nose?
The lacrimal sac is the structure on the medial aspect of each eye that drains tears into the nose. Tears produced by the eye drain through the lacrimal puncta, then pass through the canaliculi and into the lacrimal sac before flowing into the nose via the nasolacrimal duct.
What is the pathway that the lacrimal gland takes from the surface of the eye?
Tears are produced by the lacrimal gland and the accessory lacrimal glands and cover the cornea. Tears then drain out the punctum in the medial eyelids, flow down the canaliculi into the lacrimal sac. They then drain down the nasolacrimal duct into the nose at the inferior meatus (under the inferior turbinate).from the lacrimal galnd to the lacrimal canals (lacrimal puncta canaliculi) to the lacrimal sace, then the nasolacrimal duct and finally the nasal cavity

What is the correct order in the flow of tears?
Lacrimal gland, lacrimal duct, superior or inferior lacrimal canal, lacrimal sac, nasolacrimal duct, nasal cavity
What is the product of the lacrimal sac?
The lacrimal sac produces tears that help lubricate and protect the eyes by supplying them with moisture and nutrients. It also helps drain excess tears through the nasolacrimal duct into the nasal cavity.
Is the lacrimal bone and lacrimal fossa the samething?
No, the lacrimal bone is a small, fragile bone that contributes to the bony orbit of the eye, while the lacrimal fossa is a depression on the medial wall of the orbit that houses the lacrimal sac, which is responsible for draining tears from the eyes.
Where is the lacrimal duct empities into?
The lacrimal duct, also known as the nasolacrimal duct, empties into the inferior meatus of the nasal cavity, located beneath the inferior nasal concha. This duct transports tears from the lacrimal sac, which collects tears from the surface of the eye, allowing for proper drainage and preventing overflow onto the face.
Why may it b necessary to blow ones nose after having a good cry?
The tears flush across the eyeball into the lacrimal canaliculi medially, than into the lacrimal sac, and finally into the nasolacrimal duct, witch empties into the nasal cavity
What is the cpt code for excision of a lacrimal sac?
it is 68520
How do tears kill bacteria?
The lacrimal puncta/canaliculi/sac & hasolacrimal duct in the eye & accessory structures secrete and contain lysozyme which is an antibacterial enzyme(naturally occurring in tears). due to its acidity its responsible for killing some bacteria.
