Page 4: Parts of the Eye: The Cornea

The cornea is one of the only tissues in the body that does not contain blood cells to nourish or protectitself. As a result, the cornea draws nourishment from the aqueous humor - a fluid which lies behind thecornea near the front of the eye - as well as from tears. In fact, tears not only nourish the cornea, but theyalso keep it moist, protect it from infection, and help wounds to heal!
