Homeostasis, from the perspective of human physiology, refers to the innate and internal mechanisms that the body has to maintain health. "Human beings are complex, non-linear, self-organizing systems that constantly exchange energy with their surroundings in a dynamic process in order to maintain themselves." 
There are periods of development, growth, and maturation as humans are continually replacing, healing, and nourishing every aspect of themself. There are four main mechanisms that the body uses to maintain homeostasis:
