Two fluids of the eye are aqueous humour and vitreous humour.
Aqueous humour or intraocular fluid fills the front part of the eye and it is made by the ciliary body. Aqueous fluid flows out through the pupil and it is then absorbed into the blood via the eye's drainage system.
Another fluid is the vitreous humour which provides nutrition to the lens and it is also secreted by the ciliary body.
