How does integumentary exchange happen?

Integumentary exchange occurs through the skin, which acts as a barrier and interface for various substances. This process involves diffusion, where gases, nutrients, and waste products can pass through the skin's layers, primarily in organisms like amphibians that have permeable skin. Additionally, specialized structures such as sweat glands and pores facilitate the exchange of water and electrolytes. Overall, the integumentary system plays a crucial role in maintaining homeostasis by regulating temperature and facilitating the exchange of materials.
