What are the tissues that make up the skin and how do they contribute to its structure and function?

The skin is made up of three main tissues: the epidermis, dermis, and hypodermis. The epidermis is the outermost layer and provides a protective barrier against pathogens and UV radiation. The dermis contains blood vessels, nerves, and glands that regulate temperature and provide sensation. The hypodermis is made up of fat cells that insulate the body and store energy. Together, these tissues work to protect the body, regulate temperature, and provide sensation.
