The respiratory system interacts with the digestive system in the role of homeostasis. Homeostasis refers to stability, balance or equilibrium or the body's attempt to maintain a constant internal environment. The internal environment of the body is tissue fluid, which bathes all cells making up the body. The composition of tissue fluid must remain constant if cells are to remain alive and healthy.
