What are the layers of the skin, and how do they contribute to the overall health and function of this vital organ?

The skin has three main layers: the epidermis, dermis, and hypodermis. The epidermis acts as a barrier against harmful substances and helps regulate body temperature. The dermis contains blood vessels, nerves, and glands that support skin function and repair. The hypodermis provides insulation and cushioning. Together, these layers protect the body from infections, regulate temperature, and maintain overall health.
