Which structure secretes aqueous humor?

Aqueous humor is produced by the ciliary body, specifically the nonpigmented cells in the ciliary processes. This secretion fills the posterior chamber and then flows through the pupil into the anterior chamber, helping to maintain intraocular pressure and supply nutrients to avascular structures like the lens and cornea. The iris, cornea, and retina don’t produce aqueous humor; the iris controls pupil size, the cornea and retina have other functions and aren’t sites of secretion. So the ciliary body is the source.
