The term 'body layer' can be defined as the outermost layer of the body, which is known as the DERMA. The DERMA is a five-letter word that is composed of two Greek words meaning 'SKIN'. It is the protective layer of the body that helps to keep out bacteria and other harmful substances. It also helps to regulate body temperature and provide sensation. The DERMA is made up of two layers: the epidermis and the dermis. The epidermis is the outermost layer and is composed of dead SKIN cells, while the dermis is the inner layer and is composed of connective tissue, sweat glands, hair follicles, and blood vessels.
