The integumentary system is also commonly referred to as the skin system. This system includes the skin, hair, nails, and various glands. The primary function of the integumentary system is to act as a barrier to protect the body from the external environment, regulate body temperature, and provide sensory information.
The skin, being the largest organ of the body, plays a crucial role in protecting against pathogens, UV radiation, and physical injuries. Hair and nails are considered appendages of the skin and contribute to additional protective functions. The glands within this system, such as sweat glands and sebaceous glands, help in temperature regulation and secretion of substances that keep the skin moist and protected.
In summary, the integumentary system, or the skin system, is essential for maintaining the body’s overall health and well-being by providing a protective barrier and performing various regulatory functions.
