A large volume of blood is transfused to a person whose baroreceptor blood pressure
control system is
not functioning. 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 of 100 mm Hg up to 120 mm
Hg, what is the
gain of the baroreceptor system?
A. -3
B. -2
C. -1
D. 0
E. +1
F. +2
G. +3 - B
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 - A
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 - C
What 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

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

______ feedback is often referred to as a "vicious cycle" because it leads to _______
instability and
sometimes death.
