Answer 1

1. This is the study of normal functioning of a living organism and its component parts, including all its chemical and physical processes - physiology

2. The study of body functions in a disease state is known as - pathophysiology

3. This kind of explanation of a physiological process focuses on how it occurs or describes the step-by-step mechanism by which it occurs - mechanistic approach

4. This kind of approach to physiology focuses on why a process exists or speculates about its adaptive significance for the organism - teleological approach

5. If you explained blood flow as resulting from rhythmic contractions of the heart's ventricles that creates pressure waves in blood vessels, which approach would you be taking - mechanistic approach ( as it describes how the blood flows)

6. If you explained the existence of blood flow as an ideal way to distribute oxygen and nutrients to body cells and remove wastes, which approach would you be taking - teleological approach (as it describes why the blood flows)

7. Ability to keep one's internal environment relatively stable despite an ever changing external environment - homeostasis

8. The law of mass balance states that the amount of substance in the body is to remain constant, any gain must be offset by an equal loss.

9. Equilibrium - it is the state in which there is no net movement between the two compartments.

10. Disequilibrium - it is the opposite of equilibrium and is characterised by difference in concentrations in the two compartments.

11. Set point - optimal value of a variable

12. Hypothesis

13. Independent variable

14. Dependent variable

15. Control group
