Explanation

The epidermis is the outermost layer of the skin and serves as the first line of defense against the external environment. It is composed of several layers of cells, including keratinocytes, melanocytes, and Langerhans cells, and is responsible for providing protection against physical, chemical, and microbial damage. The dermis is the layer of skin beneath the epidermis and contains blood vessels, nerves, hair follicles, and sweat glands. The hypodermis, also known as the subcutaneous layer, is located beneath the dermis and is composed of adipose tissue and connective tissue.
