  • Understand, don’t memorize.
  • Draw out how the physiology works.
  • It was useful for me to draw out the mechanisms on giant sheets of paper and add to it as we went through different systems. That way you could see how each system interacted and effected on another.
  • Don’t throw anatomy notes and knowledge away! Apply what you learned in anatomy and learn WHY anatomy is there and HOW processes occur.
