1. Least to most complex structural organiẓation: chemical, cellular, tissue, organ, system,
organism
2. Homeostasis: a condition of equilibrium in the body's internal environment maintained by a regulatory
process
3. Negative feedback: disruption of homeostasis causes a chain reaction that brings the body back to normal
conditions (ex: body temperature and blood pressure)
4. Positive feedback: disruption of homeostasis causes further deviations (ex: labor and blood clots)
5. Anatomical position: hands at side, palms facing forward, feet together, and viewing anterior side of the
body
6. Supine: laying on back
7. Prone: laying on stomach
8. Sagittal plane: cuts body into left and right sides
9. Mid-sagittal plane: cuts body right down the middle
10. Frontal plane: splits body into anterior and posterior halves (front and back)
1/9
, 11. Transverse plane: splits body into upper and lower halves
