Verified step by step guidance

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.

Identify the role of the epidermis: The epidermis is the outermost layer of the skin, primarily composed of keratinocytes. It acts as a protective barrier but does not contain blood vessels.

Explore the dermis: The dermis is located beneath the epidermis and contains blood vessels, nerves, and connective tissue. It provides nourishment to the epidermis through diffusion.

Consider the hypodermis: The hypodermis, also known as the subcutaneous layer, is below the dermis and consists mainly of fat and connective tissue. It helps insulate the body and provides cushioning.

Clarify the stratum corneum: The stratum corneum is the outermost layer of the epidermis, composed of dead keratinized cells. It does not contain blood vessels and relies on the dermis for nutrients.
