Explanation: 

Detailed explanation-1: -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. This process is called accommodation.

Detailed explanation-2: -Aqueous humour is a transparent, watery fluid between the cornea and the crystalline lens. It maintains the pressure needed to inflate the eye and provides nutrition for the central cornea and lens as they do not have blood supply.

Detailed explanation-3: -Aqueous humour is made by the ciliary body. Strands from the ciliary body support the lens behind the coloured part of the eye (iris). Aqueous humour flows into the front of the eye through the pupil. Aqueous humour drains out of the eye through the trabecular meshwork.
