the “Internal Environment”
1. The most abundant type of cell in the human body is which of the following?
A. Neuron
B. Epithelial cell
C. Red blood cell
D. White blood cell
E. Vascular smooth muscle cell
F. Skeletal muscle cell
ANS: C

3. A large volume of blood is transfused to a person whose baroreceptor blood
pressure control system is not functioning and arterial blood pressure rises from the
normal level of 100 to 160 mm Hg. If the same volume of blood is infused into the
same person when the baroreceptor system is functioning and this time the arterial
pressure increases from the normal level from 100 mm Hg up to 120 mm Hg, calculate
the gain of the baroreceptor system in this person.

C. -1
D. 0
E. +1
F. +2
G. +3
ANS: B
4. Exchange of substances between the cardiovascular system and the interstitial
fluid occurs mainly in which of the following?
, A. Arteries
B. Arterioles
C. Capillaries
D. Venules
E. Veins
ANS: C
5. Which of the following substances has the highest extracellular fluid to
intracellular fluid concentration ratio for most mammalian cells?
A. Sodium ions
B. Potassium ions
C. Carbon dioxide
D. Glucose
E. Protein
ANS: A
6. Which of the following is the approximate distance from the capillaries to most cells
of the body?
A. Less than 50 angstroms
B. Less than 50 microns
C. Less than 50 millimeters
D. Less than 100 angstroms
E. Less than 100 microns
F. Less than 100 millimeters
ANS: A
7. When a person is at rest, how much time is required for the blood in the circulation to
traverse the entire circulatory circuit?
A. 1 second
B. 1 minute
C. 3 minutes
D. 4 minutes
E. 5 minutes
ANS: B
8. feedback is often referred to as a "vicious cycle" because it leads to instability and
sometimes death.
A. Positive, progressive
B. Positive, diminished
C. Negative, progressive
D. Negative, diminished

C. Increased respiration rate caused by accumulation of carbon dioxide in the blood
D. Decreased sympathetic nervous system activity that occurs in response to increased
blood pressure
ANS: A

packaging of a secreted protein.
1. Initiation of translation.
ANS: I
2. Protein sorting and packaging.
ANS: E
3. Gene transcription.
ANS: B
