Do tears drain into the nasal cavity?
Right side. Outline of bones of face, showing position of air sinuses. The nasolacrimal duct (also called the tear duct) carries tears from the lacrimal sac of the eye into the nasal cavity.

Simply so, why do you cry if you have canals that drain tears into the nasal canal?Exposure to strong fumes, wind, or even spicy foods cause a more robust tear response called reflex tearing. Tears drain from the eyes into the nasal passages through four ducts, one in each of the eyelids near the inner corners closest to the nose. The hole in each eyelid connecting to the canal is called the punctum.Furthermore, how do you drain a tear duct? The doctor enlarges the punctal openings with a special dilation instrument and inserts a thin probe through the puncta and into the tear drainage system. For adults with partially narrowed puncta, your doctor may dilate the puncta with a small probe and then flush (irrigate) the tear duct. Besides, where do tears drain? Normally, tears flow from the lacrimal glands over the surface of your eye. Tears drain into the puncta, located in the inside corners of your upper and lower eyelids. Your eyelids have small canals (canaliculi) that move tears to a sac where the lids are attached to the side of the nose (lacrimal sac).Where do tears drain upon leaving the nasolacrimal duct?After the tears leave the eye through the puncta, they drain down through a little “tube” called the nasolacrimal duct. This duct goes underneath the skin and through the bones of the face into the nose.
