"conjunctiva"的定义和意义

What is "conjunctiva"?

The conjunctiva is a mucous membrane that lines the front surface of the eye and the inner surface of the eyelids. It acts as a protective barrier, shielding the delicate structures of the eye from external irritants and infections. The conjunctiva also contains tiny blood vessels that supply oxygen and nutrients to the eye tissues. Additionally, it produces a thin layer of mucus and tears that helps lubricate the eye, ensuring smooth blinking and reducing friction. Overall, the conjunctiva plays a vital role in maintaining the health and proper functioning of the eyes.
