It is a compound tubular gland, located in the upper outer angle of orbit.

Poured into the upper outer portion of the fornix of the conjunctiva for several excretory ducts, there are spread over the surface of the eyeand tend to accumulate in the inner corner, where they are taken by the two tear ducts.

Tear ducts
One for each eyelid. Converge into a common duct which empties into the lacrimal sac ordacriocisto, this is a membrane reservoir, placed vertically on the inside of the base of the orbit, the lower portion is continuous with the nasal passage.

Near the bottom hole exists in the nasal passagefor a rally, Horner valve, a remnant of the membranous diaphragm that closes the tear ducts before birth.

THE SWEAT GLANDS

The sweat glands secrete a transparent liquid (sweat) containing...
