Question: 1 / 400

How many layers of skin does the human body have?

2 layers

3 layers

The human body has three primary layers of skin: the epidermis, dermis, and subcutaneous layer (or hypodermis).

The epidermis is the outermost layer, primarily composed of keratinocytes, and it serves as a protective barrier against environmental factors. Beneath the epidermis lies the dermis, which contains connective tissue, hair follicles, and glands. This layer provides strength and elasticity to the skin. The subcutaneous layer is the deepest layer, made up of fat and connective tissues that help insulate the body and absorb shock.

Understanding these three layers is essential for recognizing how the skin functions to protect the body, regulate temperature, and enable sensation. This foundational knowledge is crucial for anyone working in healthcare, particularly in personal support work, as it informs practices related to skin care and wound management.
