Physiology
Study of functions
Principle of Complementarity
Shape determines function
Structural Levels of Organization

Homeostasis
Prevents disease, the ability of the body to maintain a relatively stable internal environment despite outside changes. Think constant adjustments, dynamic state of equillibrium
