Cardiovascular Physiology Quiz
Questions and Answers
Baroreceptors in the aortic arch and carotid sinus - ANS-Which of the following, is
sensitive to blood pressure fluctuations in the body?
at the beginning of ventricular systole - ANS-The mitral valve closes:
at the end of ventricular systole - ANS-The semilunar valves close:
true - ANS-The P wave in an ECG represents atrial depolarization
increasing EDV, hence increases stroke volume - ANS-Increased venous return during
exercise increases the cardiac output by:
Increasing their stroke volume more than their heart rate - ANS-Athletes normally have
a high vagal tone and during exercise compensate by:
False - ANS-The parasympathetic system increases the rate and force of contraction of
the heart.
increasing excretion of sodium and water - ANS-The hormone ANP regulates blood
pressure by:
There is sympathetic stimulation, which increases heart rate and also causes
vasoconstriction to raise the blood pressure - ANS-Which of the following statements
describes what happens in shock due to decreased blood volume?
Peripheral resistance - ANS-In a person having atherosclerosis, blood pressure rises
because of an increase in:
Tachycardia - ANS-Increase in the heart rate is called:
There would be pedal edema and organs like the liver would exhibit tenderness. - ANS-
Severe pulmonary stenosis will prevent blood from leaving the right ventricle and so the
end systolic volume in the right ventricle would increase and could lead to right sided
failure. What would be the result of this failure?
True - ANS-EDV-SV = ESV
where EDV = end diastolic volume; SV = stroke volume; ESV = end systolic volume
