, How do you calculate kcal burned during exercise? - ✔✔multiply total VO2 consumed
by 5
What is homeostasis? - ✔✔maintenance of a constant internal environment
normal resting conditions
What is a steady state? - ✔✔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? - ✔✔to regulate some physiological
variable at or near a constant value
What is a biological control system? - ✔✔series of interconnected components that serve
to maintain a physical or chemical parameter at or near a constant
What does a receptor do? - ✔✔capable of detecting changes
What does an integrating centre do? - ✔✔assesses input and initiates a response
What does an effector do? - ✔✔corrects changes to internal environment
What system do most biological systems operate via? - ✔✔negative feedback system
What is a negative feedback system? - ✔✔the response of the control system is opposite
to the stimulus
the response reverses the initial disturbance in homestasis
