AI overview

Tears are a clear fluid produced by glands in the eyes of all land mammals, made up of water, electrolytes, proteins, lipids, and mucins that coat the eye's surface. They come in four different types—basal, closed eye, emotional, and reflex—each with distinct compositions, and their production can increase dramatically in response to irritation.

Eine Träne, dichterisch und regional auch noch Zähre genannt, ist eine salzhaltige Körperflüssigkeit, die die Tränendrüsen von Menschen und Säugetieren ständig absondern. Sie dient der Reinigung des Bindehautsacks und der Befeuchtung und Ernährung der Hornhaut. Außerdem verbessert sie die optischen Eigenschaften der Hornhautoberfläche, indem sie die physiologischen Unregelmäßigkeiten durch Niveauunterschiede ausgleicht. Das Tränensekret besteht aus drei Schichten.
