Question

epidermis The epidermis is the body's first line of defense against infection, external injury, and environmental stresses. ˌɛpɪˈdərməs

Accepted Answer

The outer layer of the skin. Epidermis includes the Greek prefix epi-, meaning “outer” (see EPI); thus, the epidermis overlies the dermis, or inner layer of skin. The epidermis itself consists of four or five layers; the outermost layer is made of dead cells, which are being shed continuously. The epidermis acts as a physical barrier—a protective wrap over the body's surface, which, by preventing water loss, allows vertebrates to live on land
