Did You Know ? How You Cry

Repost from @mr.brainboost • That tiny opening on your eyelid isn’t producing tears, it’s part of your eye’s drainage system. Tears are made by the lacrimal gland, then flow across your eye before draining through small ducts into your nose. That’s why your nose runs when you cry. #eyefacts #tearsscience #anatomy101 #didyouknow #healthfacts
