    The ability to sense change in the environment and then react to them. 

    Also known as Irritability
  5. Metabolism:
    A broad term that refers to all chemical reactions that occur within body cells 

    -Depends on digestive, respiratory, and muscular systems to bring nutrients to cells 

    -Regulated by hormones
  6. Homeostasis:
    The body's ability to maintain relatively stable internal condition
  7. Homeostasis Control Mechanism
    • 1. Receptor: A type of sensor that responds                     to stimuli 
    • 2. Control Center: Determines the level at                               which a variable is to be                             maintained
