Human Physiology: An Integrated
Approach Ch 1
1.1 Define Physiology - ANS the study of the normal functioning of a living organism
and its component parts, including all its chemical and physical processes
1.2 List the levels of organization from atoms to the biosphere. - ANS 1. Atoms
2. Molecules
3. Cells
4. Tissues
5. Organs
6. Organ Systems
7. Organisms
8. Populations of one species
9. Ecosystem of different species
10. Biosphere
1.6 Define homeostasis. What happens when homeostasis fails? - ANS The ability of
the body to maintain a relatively constant internal environment. If homeostasis fails,
then normal function is disrupted and a diseased state, or pathological condition may
result.
1.7 Name and describe the two major compartments of the human body. - ANS
Intracellular Fluid Compartment - Within Cells
Extracellular Fluid Compartment - Outside of Cells
1.11 Distinguish between equilibrium and steady state. - ANS Equilibrium implies that
the composition of the body compartments is identical. The two fluid compartments are
not identical, but exists in a state of relatively stable disequilibrium.
