Aqueous Humour
Aqueous Humour (pronounced: /ˈeɪkwiəs ˈhjuːmər/) is a clear, watery fluid located in the anterior and posterior chambers of the eye, between the cornea and the lens.
Etymology
The term "Aqueous Humour" is derived from the Latin words 'aqua' meaning water, and 'humor' meaning fluid. The term was coined in the ancient times when the body was believed to contain four basic substances, also known as the four humours: blood, phlegm, black bile, and yellow bile.
Function
The primary function of the Aqueous Humour is to provide nourishment to the cornea, lens, and other parts of the eye that do not have a direct blood supply. It also helps to maintain the intraocular pressure and the shape of the eye.
Related Terms
- Intraocular Pressure: The fluid pressure inside the eye, maintained by the balance between the production and drainage of Aqueous Humour.

- Cornea: The clear front surface of the eye that allows light to enter.
