Homeostasis is the ability to maintain a relatively stable internal environment in an ever changing external world. Ex: Thermoregulation which is the maintaining of body temperature

Negative feedback is when the body is not in the optimal ranage, and reacts to get back into the normal range Ex: Starvation

Positive feedback is when the initial stimuli causes an increasing reaction from the body. Ex: Nursing a baby
