The ciliary body is a ring of tissue that encircles the lens. The
ciliary body contains smooth muscle fibers called ciliary muscles
that help to control the shape of the lens. Towards the posterior
surface of the lens there are ciliary processes which contain
capillaries. The capillaries secrete the fluid (aqueous humor) into
the anterior segment of the eyeball.
