1 Anatomy and Physiology I College of the Desert Biology 013 Alexa Franco Sawa, Ph.D. 2 The Human Body: An Orientation Chapter 1 3 Goals De±ne anatomy and physiology How are they complementary? Explain the 6 structural levels of organization of the human body Name the 11 organ systems of the body What function(s) does each perform? Learn the language of anatomy 4 Anatomy Studies the structure of body parts Easy to understand because it is concrete You can see, feel, and examine where parts are and how they are connected 5 2 Types of Anatomy Gross Anatomy Large structures visible to the naked eye Brain, skeleton… Microscopic Anatomy Small structures visible only under a microscope Nerve cells, bone cells… 6 Physiology Studies the functions of the body How do the body parts do their jobs? 7 Example of Physiology Neurophysiology How the nervous system works Trickier because you can’t usually “see” what is going on All the action usually occurs at the molecular and cellular level 8 Complementarity of Structure and Function Function always re²ects structure Physiology always re²ects anatomy What a structure can do depends on its form A body part can only do its job if it has the right structure 9 Structure and Function Go Together Example: Bones can support and protect because they are made of hard minerals 10 Practice Test Questions
