ciliary body
lens

Explanation:

The ciliary body is responsible for secreting the aqueous humor. The aqueous humor is a clear, watery fluid that fills the front part of the eye. It has several important functions, including providing nutrients to the cornea and lens, maintaining intraocular pressure, and helping to maintain the shape of the eye. The lens is a transparent structure that helps to focus light on the retina. The iris is the colored part of the eye that controls the amount of light entering the eye by adjusting the size of the pupil. The vitreous humor is a gel - like substance that fills the back part of the eye and helps to maintain the shape of the eye.
