Final answer:
Tears are drained from the cornea into the lacrimal sac and then flow into the nasal meatus of the nasal cavity through the nasolacrimal duct.
Step-by-step explanation:
Tears flow over the cornea and drain via the lacrimal sac into the c. nasal meatus.
The eye's lacrimal system is responsible for the production and drainage of tears. When tears flow over the cornea, they serve the important function of keeping the eye moist and healthy by removing debris and maintaining a clear surface for vision. After tears accomplish their function, they must be drained from the surface of the eye. This drainage occurs at the medial corner where the tears enter the lacrimal puncta.
These small openings act as the entry point for tears to move into the lacrimal ducts and subsequently into the lacrimal sac. From there, the fluid travels down the nasolacrimal duct, which runs downward from the medial-anterior orbit to the nasal cavity. The duct terminates behind the inferior nasal concha. It is in this location—the nasal meatus—that tears are finally dispelled into the nasal cavity.
