könnycsatornákba

"Könnycsatornákba" is the Hungarian plural form for "tear ducts." Tear ducts, also known as lacrimal ducts or lacrimal canaliculi, are a crucial part of the eye's drainage system. They are small channels that collect excess tears from the surface of the eye and transport them to the lacrimal sac, and then down into the nasal cavity.

The primary function of tear ducts is to facilitate the proper drainage of tears. Tears are essential for lubricating the eye, washing away debris, and protecting against infection. When we blink, tears are spread across the surface of the eye. The excess fluid then flows towards the inner corner of the eye, where the opening of the tear ducts is located.

There are typically two tear ducts, one for each eye, situated in the upper and lower eyelids near the nose. These tiny tubes begin as puncta, small openings, and widen into canaliculi. These then converge to form the common canaliculus, which empties into the lacrimal sac. From the lacrimal sac, the tears descend through the nasolacrimal duct into the nasal cavity. This is why crying can sometimes lead to a runny nose.

Obstructions or inflammation of the tear ducts, known as dacryocystitis, can lead to excessive tearing (epiphora), eye discharge, and pain. These conditions may require medical intervention to restore proper tear drainage. In summary, "könnycsatornákba" refers to the vital anatomical structures responsible for draining tears from the eyes.
