What is homeostasis? - ANS maintenance of a constant internal environment
normal resting conditions
What is a steady state? - ANS the balance between demands placed on the body and the
physiological response to those demands
What is the goal of the control systems of the body? - ANS to regulate some physiological
variable at or near a constant value
What is a biological control system? - ANS series of interconnected components that serve to
maintain a physical or chemical parameter at or near a constant
What does a receptor do? - ANS capable of detecting changes
