DISCUSSION. 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.he tear glands are located under your upper lids, and when stimulated, produce tears to form a thin film over your eyeballs.

The lacrimal glands are paired almond-shaped glands, one for each eye, that secrete the aqueous layer of the tear film. They are situated in the upper, outer portion of each orbit, in the lacrimal fossa of the orbit formed by the frontal bone. Inflammation of the lacrimal glands is called dacryoadenitis. The lacrimal gland produces tears which then flow into canals that lead to the lacrimal sac. From this sac, the tears drain through the lacrimal duct into the nose. Anatomists divide the gland into two sections. The smaller palpebral portion lies close to the eye, along the inner surface of the eyelid; if the upper eyelid is everted, the palpebral portion can be seen.
