Step-by-step explanation:
Human skin is made up of three layers: the epidermis, dermis, and subcutaneous tissue. The epidermis is the outermost layer and primarily functions to protect the body from the external environment. The dermis is the middle layer and contains structures such as hair follicles, sweat glands, and blood vessels. The subcutaneous tissue, also known as the hypodermis, is the deepest layer and is mainly composed of fat cells that provide insulation and cushioning for the body.
