Tears flow from tear glands into your eyes through tiny tear ducts. The tear glands are located under your upper lids, and when stimulated, produce tears to form a thin film over your eyeballs. Every time you blink the film spreads over your eyes to keep them moist and free of dust and other irritants. Whether you are awake or asleep, happy or sad, this salty fluid is always flowing from the tear glands.
Besides protecting your eyes, the tear glands produce more fluid when your eyes are irritated. These extra tears are called reflex or irritant tears. And, when something makes you happy or sad, your tear glands will produce emotional tears.
Used tears then drain down into two tiny openings on the brim of your upper and lower eyelids at the inner edge of your eyes, which lead to the nasolacrimal tear ducts next to the bridge of your nose. From there, they are channeled into your nasal cavity where they are swallowed or blown out with other nasal fluids. If there are too many tears, they will overflow your lower lid and run down your cheeks.
They come from a structure called the Lacrimal Gland locate in the sperior lateral part of the eye socket. Tears are distibuted onto the eyeball by the Lacrimal Ducts. They are then spread by the eyelids which eventually push the fluid Medially towards the Lacrimal lake (technical term for the tear drop often seen under the eye). From the lacrimal lake the Cannaliculi (what most people, including the answer above, see as the tear ducts) drain the fluid into the Lacrimal sac from which the Nasolacrimal Ducts carry the fluid into the middle meatus of the nose.
The eye's tears are composed of three layers: oil, water and mucous. The outermost oily layer is produced by the meibomian glands which line the edge of the eyelids. The watery portion of the tear film is produced by the lacrimal gland. This gland lies underneath the outer orbital rim bone, just below the eyebrow. The mucous layer comes from microscopic goblet cells in the conjunctiva. With each blink, the eyelids sweep across the eye, spreading the tear film evenly across the surface. The blinking motion of the eyelids forces the tears into tiny drains found at the inner corners of the upper and lower eyelids. These drains are called puncta (plural for punctum). The tear film travels from the puncta into the upper and lower canaliculus, which empty into the lacrimal sac. The lacrimal sac drains into the nasolacrimal duct which connects to the nasal passage. This connection between the tear production system and the nose is the reason your nose runs when you cry. Some patients can actually taste eye drops as they drain from the nasal passage into the throat.

Tears are formed when crying because of fluid from the sinuses. The fluid runs up tear ducts to the corners of the eyes. Too much pressure in that area and the tears run.
