1. Chapter 1: An introduction to Anatomy and Physiology

2. Living Characteristics Responsiveness Irritability—respond to changes in environment Ex: Dog barks Adaptability—long-term changes Ex: Dog grows thick fur for winter

3. Living Characteristics cont… Growth Reproduction Movement (Internal or External) Metabolism—all chemical reactions in the body

4. The Science of Anatomy Anatomy—”a cutting open” Study of internal and external structures Physiology—Study of how an organism performs their functions

5. Anatomy Gross Anatomy—macroscopic Features visible with naked eye Microscopic Anatomy Structures that cannot be seen without a microscope Cytology—study of cells Histology—study of tissues Groups of cells with specific functions

6. Physiology Cell physiology—study of the function of cells Special physiology—study of the function of organs Systemic physiology—study of organ systems Pathology—study of diseases on organs

7. Levels of Organization Chemical (Molecular) Level Atoms—smallest units of matter Molecules—2 or more atoms Cells—smallest living units Tissues Organs Organ Systems Organism
