Illustrate the Structure and functions of aqueous humour

Aqueous humour is a clear fluid that fills the anterior and posterior chambers of the eye and permeates the vitreous. It supplies the intra-ocular pressure required for the eye and provides nutrients and oxygen to the internal eye structures (e.g., lens, iris and cornea). In addition, the aqueous humour functions in eliminating metabolic waste. The aqueous provides a clear media which allows rays of light to pass through uninterrupted to the retina permitting clear vision.
