Objectives
After completing this chapter, you should be able to
1. define the terms anatomy and physiology.
2. define the following levels of structural organization: chemical,
cellular, tissue, organ, system and organism.
3. identify the 11 systems of the human body, list
representative organs of each system, and describe the major
functions of each system.
4. identify the basic life processes of the human body.
5. define the term homeostasis, and explain the effects of stress
on homeostasis.
6. describe the components of a feedback system.
7. compare the operation of negative and positive feedback systems.
8. explain the relationship between homeostasis and disease.
9. describe the anatomical position, and compare common and
anatomical terms used to describe various regions of the
human body.
10. define the terms describing directions and anatomical planes
used in association with the human body.
11. list, by name and location, the principal body cavities and the
organs contained within them.
