what is the function of the conjunctiva in the eye
Conjunctiva The conjunctiva helps lubricate the eye by producing mucus and tears, although a smaller volume of tears than the lacrimal gland.[6] It also contributes to immune surveillance and helps to prevent the entrance of microbes into the eye.
Aqueous humour The aqueous humour is a transparent, watery [1] fluid similar to plasma, but containing low protein concentrations. It is secreted from the ciliary epithelium, a structure supporting the lens.[2] It fills both the anterior and the posterior chambers of the eye, and is not to be confused with the vitreous humour, which is located in the space between the lens and the retina, also known as the posterior cavity or vitreous chamber.
