Describe how science develops new principals | using detailed observations and vigorous tests, or experiments, to analyze each idea or hypothesis until a reasonable conclusion can be made |
Define anatomy and phisiology | 2. Anatomy is the study of the structure of an organism and the relationships of its parts. Physiology is the scientific study of the body functions of the living organism and its parts. |
List three ways phisiology can be subdivided as a scientific discipline | (1) the type of organism involved, (2) the organizational level studied, and (3) a specific, or systemic, function being studied |
What name is used to describe the study of the body that focuses on groups of organs that have a common funtion? | systemic anatomy |

What are the seven levels of organization? | The seven levels of organization are chemical, organelle, cellular, tissue, organ, system, and organism |
