Definition for Aqueous humor
From Biology Forums Dictionary
Aqueous humor is the clear fluid present in the front part of the eye, between the cornea and the eye lens. If you look into your eyes in the mirror, or someone else’s, you can see the transparent cornea first, the colored or pigmented iris behind and the clear lens through the pupil. The space enclosed between the cornea and the lens is called the anterior segment and contains the aqueous humor.
