A) Helps in transmitting impulses to the brain.
B) Protect the eyeball from collapsing.
C) Keeps the cornea moist and gives definite shape to the eyeball.
D) All

Answer 1

Hint: Aqueous humour is the fluid produced in the eye & it provides nutrition to the eye.
Aqueous humour is very thin watery fluid which is located in the anterior and posterior chambers of the eye.

Complete answer:
The aqueous humour is a transparent watery fluid similar to plasma, but containing low protein concentrations. It is secreted from the Ciliary body, a structure supporting the lens and it occupies the space between the crystalline lens and the cornea of the eye.
The aqueous humour resembles very much with the blood plasma in composition but it contains less protein and glucose & also it is optically clear.
The aqueous humour plays an essential role in the health of your eye (any eye ) & as well as nourishing the cornea and the lens by supplying nutrition .
These nutrients contain nutrients such as amino acids and glucose.
The function of aqueous humour is to :-
Maintain the intraocular pressure
Transport the ( vitamin $$C$$) in the front segment to act as an antioxidant agent.
To provide inflation for expansion of the cornea,
Aqueous humour increases protection against dust, wind, and also from pathogens.

Hence option (D) is the correct answer.

Note: Maintains the intraocular pressure and inflates the globe of the eye.
 It is this hydrostatic pressure which keeps the eyeball in a roughly spherical shape and keeps the walls of the eyeball taut.
Provides nutrition for the vascular ocular tissues, posterior cornea , lens, and anterior vitreous.
