How does your tearducts know when to produce tears.

In: Biology

The brain stem controls things like breathing, digestion, and tear production.

There’s a medical condition called anencephaly where babies are born without a brain. Sometimes these babies will show typical baby traits and can breathe, cry, or grab your finger.

These are things we can do without thinking about it.

Tears are actually produced by little glands under your eyelid.

The tearduct is just a tube that connects the bottom of your eye to your nose to drain liquids.
