  • Interdependent
  • Structure determines what functions are possible
• Cannot be separated from anatomy because “Physiology is Anatomy in Motion.”


  Interdependent
• For example, the lungs are not muscular chambers like the heart and so they can’t pump blood through the body, but because the walls of their air sacs are very thin, they can exchange gasses and provide oxygen to the body.

  Structure determines what functions are possible
