2. What is Anatomy?  ana = apart or away  tomos = to cut  Study of structure  Two types:  Gross  Microscopic

3. What is Physiology?  Study of function- attempts to answer how & why

4. So What Are We Doing Here?  Studying the marriage of structure & function!

5. Levels of Structural Organization 1. Chemical level

6. Levels of Structural Organization 2. Cells – basic unit of structure & function

7. Levels of Structural Organization 3. Tissues – similar cells with a common function

8. Levels of Structural Organization 4. Organs – performs a specific function & are made of two or more tissue types

9. Levels of Structural Organization 5. Organ systems – Different organs that work closely together

10. Levels of Structural Organization 6. Organismal level – Many organ systems make up an individual
