What does the integumentary system consist of?

The integumentary system primarily consists of the skin and its accessory organs, which include hair, nails, and various glands (such as sebaceous and sweat glands). This system plays a critical role in protecting the body from external damage, regulating temperature, and facilitating sensation. The skin acts as a barrier to pathogens, injuries, and harmful substances while also having a role in immune response. Accessory organs contribute to the overall function of the integumentary system, enhancing the skin's protective capabilities and contributing to homeostasis. Understanding this system's components is essential for recognizing its vital functions in maintaining overall health and well-being.
