Question

Where do they come from the heart or the face or what?
REALLY CONFUSED!

Answer 1

Tears come from tear ducts in the inner areas of the eyes next to the bridge of your nose. The tears themselves come from glands behind your eyelids.

Answer 2

you brain triggers them

Tears are the salty fluid that lubricates and helps protect the cornea, the membrane that covers the front of the eye. Tears flow into the eye through ducts from tiny glands located under the upper eyelids and are spread over the eye each time a person blinks, which is about every six seconds. Tears keep the eye moist and free of dust and other eye irritants.

Tears provide five functions:

Keeping the epithelium moist, thereby protecting the outer covering of the eye from damage because of dryness
Creating a smooth optical surface on the front of the cornea
Acting as the main supplier of oxygen and other nutrients to the cornea
Carrying waste products away from the cornea
Providing enzymes that destroy bacteria that can harm the eye

Answer 3

You almost have some good answers, but the tear glands are located laterally, and the tears sweep across the eyes to the tear ducts, where they drain down into the nose, which is why you sniffle when you cry.

Answer 4
