TEARS are FROM the UPPER EYELIDS

Did you ever notice that our tears don't ever fall down unless we closed our eyes or blinked? I didn't, until my immunology teacher told me about it. Most of us think that our tears originate from the corner of our eye near our nose or on the lower eyelid. However, this is actually not the case. Our lacrimal glands, which are responsible for producing tears, are located on our upper eyelid, the side farther away from our nose. That's why we don't cry until we blink. When we blink, this is when the tears traverse our eyes. It's just strategic to put the lacrimal glands on the upper eyelids because the tears somewhat have an antibacterial property and has the capacity to wash out dirt or something like that. So when we cry, we also cleanse our eyes from top to bottom. Haha. Imagine if our lacrimal glands were located in our lower eyelids. The tears would have to defy gravity to wash out a dirt on the upper part of our eye. Do you wonder why our noses get stuffed when we cry? It's because the tears in the corner of our eye near the nose, enter the lacrimal duct, which also opens to the nose. Hence, this is why gooey eeeky fluid comes out of our nose when we cry. Then, before you know it, you can't breath anymore! Haha. I just had to share this. It's something that I found a little bit surprising in my college life. I hope you get surprised with this tiny piece of information as well. :)
