The largest organ in the body is the skin. Serving as the body's protective barrier, the skin plays a critical role in regulating temperature, providing sensory information, and preventing the loss of fluids. It consists of three main layers: the epidermis, dermis, and hypodermis, each with specific functions. The skin also houses various structures such as hair follicles, sweat glands, and sebaceous glands. In addition to its protective properties, skin health is vital for overall well-being, influencing both physical and emotional aspects of health.
