And the aqueous humor consists predominantly of water, but it also consists of a low concentration of proteins as well as other things. And the aqueous humor basically maintains the pressure inside this region inside the eye. Now, the ciliary body, which is this portion here, and this portion here, basically contains the ciliary processes which actually synthesize and secretes our aqueous humor, the fluid known as aqueous humor. And they secrete that fluid through a canal known as the canal of schlem. So we have this anterior cavity that contains our aqueous humor, that is a fluid that maintains that pressure inside this region of our eye. Now, the next portion is our pupil.
