Anatomy- the study of the physical structures of the body and the relationships among body structures. Physiology- the study of the function of body structures and their complex interactions. Homeostasis- the ability to maintain a relatively stable internal environment; allows the body to maintain a physiological parameter, such as body temperature, in a normal range around a predetermined set point. Example: body corrects an increase in body temperature by sweating. Negative feedback- opposes the original stimulus; thus minimizes the change that activated the system. Positive feedback- enhances the change that initiated the response.
