The ciliary body has three functions: accommodation, aqueous humor production and resorption, and maintenance of the lens zonules for the purpose of anchoring the lens in place. In this way, what is the function of the ciliary muscle and body? The ciliary body is a circular structure that is an extension of the iris, the colored part of the eye. The ciliary body produces the fluid in the eye called aqueous humor. It also contains the ciliary muscle , which changes the shape of the lens when your eyes focus on a near object. Also Know, where is the ciliary body? The ciliary body is anatomically located anterior to the iris and is involved in regulating three major functions in the eye: (i) it secretes aqueous humor, which passes in front of the lens and drains out of the eye via tubules called the trabecular meshwork and canal of Schlemm near to the junction of cornea and iris Furthermore, what is the function of the iris?
