Verified step by step guidance

1. Understand the structure of the skin: The skin is composed of three main layers - the epidermis, dermis, and hypodermis. Each layer has distinct functions and characteristics.
2. Identify the function of the epidermis: The epidermis is the outermost layer of the skin, primarily responsible for protection. It is composed of keratinized cells that form a barrier against environmental damage.
3. Recognize the process of shedding: The epidermis undergoes a continuous process of cell turnover, where dead cells are shed from the surface. This process helps remove microbes that may be attached to these cells.
4. Differentiate between the layers: The dermis is located beneath the epidermis and contains connective tissue, blood vessels, and nerves. The hypodermis, or subcutaneous layer, is primarily composed of fat and connective tissue. Neither of these layers is involved in shedding dead cells.
5. Consider other structures: Mucous membranes line various cavities in the body and secrete mucus, but they do not shed dead skin cells. Hair follicles are structures within the skin that produce hair, but they are not involved in the shedding of dead cells.
