Which structure is the mucous membrane that protects the eye's surface?

The mucous membrane that protects the eye's surface is the conjunctiva. This specialized tissue covers the inner eyelids and the white part of the eyeball, providing both a barrier and lubrication to keep the eye moist. Its role is critical as it helps to shield the eye from pathogens and harmful substances, while also playing a part in the immune response to potential threats. The conjunctiva contains mucous-producing cells that contribute to tear film stability, which is essential for maintaining eye health and comfort. Understanding the function of the conjunctiva highlights its importance in overall ocular protection and health.
