QUESTIONS AND CORRECT ANSWERS
Question:
1. how things work/ maintenance of homeostasis
Answer:
Physiology
Question:
2. Functional Units
Answer:
Many organs are organized into small, similar sub units often referred to as
___________, each performing the function of the organ.
Question:
3. how something goes wrong/ loss of homeostasis (disease)
Answer:
Pathophysiology
Question:
4. PLASMA percentage of total body water?
Answer:
7%
Question:
5. interstitial fluid percentage of total body water?
Answer:
26%
Question:
6. intracellular fluid percentage of total body water?
Answer:
67%
, Question:
7. If a person rapidly ingested 1 L of water, it would
distribute freely between the body's 3 major fluid
compartments. What volume matches with which
compartment?
Answer:
70 mL - plasma
260 mL - interstitial fluid
670 mL - intracellular fluid
Question:
8. True or False. Most body cells are in contact with the interstitial fluid.
Answer:
True
Question:
9. True or False. Most physiological variables are maintained within a normal range
that favors the survival of body cells.
Answer:
True
Question:
10. Most physiological variables in the extracellular fluid vary
widely with changes in the external environment
Answer:
False
Question:
11. Saying that a variable such as blood glucose is
"homeostatic" means that is has a constant value over a
long period of time.
Answer:
False
Question:
12. When a variable such as blood pressure increases, above
normal, homeostatic mechanisms generally
overcompensate and make the variable become below
normal.
Answer:
False
