Tear duct anatomy

the eye blinks, the lids push the tears across the eye into the drains (puncta)
at the inner corner. The drains empty into channels (canaliculi) that connect
the eye with the nose. The channels drain into tear sacs (lacrimal sacs) that
lie beside the nose. The sacs narrow into tear ducts (lacrimal ducts) that
drain through the nasal bone into the nostrils.
