Which does not describe cardiac output?
It is determined by body size and aerobic fitness
The amount of blood pumped by the heart each minute
It is the amount of blood pumped out of the heart each beat
It is the product of heart rate and stroke volume
What is stroke volume?
the volume of oxygen transported in the blood
the volume of blood pumped out of the heart each minute
the volume of blood pumped out of the heart in each beat
the number of beats per minute
What conduction system fires an impulse in order for the atria to contract?
SA node
AV node
Bundle of his
Purkinje Fibers
Identify the 3 occurrences during diastole or relaxation phase of cardiac cycle?
Atrial-ventricular valves open
Semi-lunar valves closed
Pressure in ventricles is higher than atria
Blood leaves atriums and fills the ventricles
Mr. Charles had his BP checked and the result is 110/70 mmHg. He then used the result in order to compute for the mean arterial pressure. Which of the following is the correct result of his computation of his MAP?
63.32 mmHg
73.32 mmHg
83.32 mmHg
93.32 mmHg

10.9 liters per minute or 10,900ml per minute
13.9 liters per minute or 13,900ml per minute
11.9 liters per minute or 11,900ml per minute
9.9 liters per minute or 9,900ml per minute
Which of the following is applying the correct sequence of the heart’s electrical impulse?
AV node → ventricles → SA node → AV bundle - Purkinje fibers → Atria
SA node → ventricles → AV bundle - Purkinje fibers → AV node → Atria
AV node → ventricles → AV bundle - Purkinje fibers → SA node → Atria
SA node → Atria → AV node → AV bundle - Purkinje fibers → Ventricles
