What is secreted into the posterior chamber of the eye by the epithelium on the inner surface of the ciliary body?

The ciliary body is a ring shaped tissue inside the eye that would divide the posterior  chamber from the vitreous body. It contains the ciliary muscle, vessels, and the fibrous connective tissue. The folds on the inner ciliary epithelium are called ciliary processes, and these then secrete aqueous humor into the posterior chamber. The aqueous humor flows through the pupil into the anterior chamber.
