The volume of blood pumped from the left ventricle with each heartbeat

• Heart Rate

• Stroke Volume

• Cardiac Output

An increased volume of blood returning to the heart leads to an increased end-diastolic volume in the ventricles and therefore greater stretch on the ventricular walls. What is this known as?

• Frank Starling Law

• Venous Return

• Stroke Volume

• Cardiac Output

During sub-maximal exercise what happens to the force of the ventricular contraction?

• Increases

• Decreases

What is the volume of blood ejected by the ventricle in one minute called?

• stroke volume

• cardiac cycle

• coronary volume

• cardiac output

How is cardiac output calculated?

• Cardiac output = blood pressure x heart rate

• Cardiac output = heart rate / stroke volume

• Cardiac output = heart rate x stroke volume

• Cardiac output = stroke volume / heart rate

blood flow is measured in

• mm/hg

• ml/min

• beats/min

• mm/min

What is the volume of blood ejected from the ventricles during each contraction called (term)?

With consistent participation in cardiovascular exercise that includes both progression and overload, over time there will be:

• An increase in HR & SV

• A decrease in HR & SV

• An increase in HR & decrease in SV

• An increase in SV & decrease in HR

When Alex was sprinting yesterday, she had a heartbeat of 170 bpm and a stroke volume of 70 ml. Calculate her cardiac output.

• 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
