The linings of natural body openings such as the mouth, nose, rectum, genitals, and eyes are called

Mucous membranes line natural body openings and act as a protective barrier. They form the inner surfaces of the mouth, nose, eyes, rectum, and genitals and continually produce mucus to keep these surfaces moist and to trap microbes. This mucus layer helps prevent infection by blocking and helping remove pathogens. The epidermis is the outer skin, glands are secretory organs, and muscles are for movement, so none of those describe the lining of these openings.
