The tear gland of the eye. The tears are carried from this factory b little ducts (b) and are poured over the surface of the eye. They serve to keep the eye moist, so that it can be moved about in its socket easily by the muscles. They also serve to wash out substances that get into the eye. The tears go into openings (c c) and pass through two ducts which unite in one (d e) which ends in the nose.
