What are some of the structures on this wrench? These are all structures, but what do they do? Anatomy = STRUCTURE Physiology = FUNCTION Now we have identified the anatomy and physiology of this tool! The Human BodyAn Orientation Anatomy Study of the structure and shape of the body and its parts Physiology Study of how the body and its parts work or function Form Fits Function Form = ANATOMY Bones Muscles Tendons Function = PHYSIOLOGY What it does How it works How it operates AnatomyLevels of Study What is gross anatomy?
