Why does the body need to maintain optimal conditions? The body needs to maintain optimal conditions for optimal enzyme action and cell function.
Homeostasis relies on automatic control systems.
In what order are signals passed along the control system?
Receptor—-> coordination center—->effector
What is the role of a coordination center? Interprets changes and organises a response.
