Question: Homeostasis
Answer:
Body's ability to maintain a stable (not constant) internal conditions with a changing
enviroment
Question: What are the internal parameters?
Answer:
Temperature, pH, blood pressure, HR, water and solute balance
Question: Set point
Answer:
narrow range in which the body maintains any particular physiological paramater
Question: Negative feedback
Answer:
The physiological process by which a parameter is returned to it's set point
Question: Circulatory system
Answer:
heart, blood, blood vessels
