Detailed explanation-1: -The orbit, eyelashes, eyelids, conjunctiva, and lacrimal glands help protect the eyes.

Detailed explanation-2: -The lacrimal glands produce tears to moisten and cleanse the eye.

Detailed explanation-3: -Meibomian glands (also called tarsal glands, palpebral glands, and tarsoconjunctival glands) are sebaceous glands along the rims of the eyelid inside the tarsal plate. They produce meibum, an oily substance that prevents evaporation of the eye’s tear film.

Detailed explanation-4: -The eyes and ears and their accessory structures are the receptor organs. The eyes give us our sight. They are the most important sense organs of the body. The ears are the receptor organs that enable us to hear and maintain balance.

Detailed explanation-5: -Half of the inner ear is used for hearing (the cochlea) and the other half is used for balance (the labyrinth). If the labyrinth or the nerve that connects it to the brain is malfunctioning, dizziness can result.
