Chapter 1 Objectives to be Assessed
  • 1. Define anatomy and physiology and explain how
    they are related.
  • 2. List and describe the major characteristics
    of life.
  • 3. List and describe the major requirements of
    organisms.
  • 4. Define homeostasis and explain its importance
    in survival.
  • 5. Describe a homeostatic mechanism.
  • 6. List the levels of organization in the human
    body

Chapter 1 Objectives to be Assessed
  • 7. Identify the locations of the major body
    cavities.
  • 8. List the organs located in each major body
    cavity.
  • 9. Name and identify the locations of the
    membranes associated with the thoracic and
    abdominopelvic cavities.
  • 10. Name the major organ systems and list the
    organs associated with each.
  • 11. Describe the general function of each organ
    system.
  • 12. Properly use the terms that describe
    relative positions, body sections, and body
    regions.
