What is the relationship between cardiac output and stroke volume during a warm-up?

• Cardiac output: elevated, Stroke volume: decreased

• Cardiac output: maintained, Stroke volume: elevated

• Cardiac output: decreased, Stroke volume: elevated

• Cardiac output: elevated, Stroke volume: elevated

Which results in the highest cardiac output?

• Heart rate: elevated, Stroke volume: decreased

• Heart rate: maintained, Stroke volume: elevated

• Heart rate: decreased, Stroke volume: elevated

• Heart rate: elevated, Stroke volume: elevated

What is the cardiovascular response during the first 5 minutes after completing a cycle race?

• Cardiac output remains constant, heart rate decreases, stroke volume increases

• Cardiac output decreases, heart rate decreases, stroke volume decreases

• Cardiac output increases, heart rate increases, stroke volume increases

• Cardiac output remains constant, heart rate remains constant, stroke volume remains constant

The graph shows the changes in heart rate and stroke volume as exercise intensity increases. Which statement best describes the effect on cardiac output as an individual reaches maximal exercise?

• A. The increase in cardiac output is due solely to increased stroke volume.

• B. Cardiac output remains unchanged due to increased heart rate.

• The increase in cardiac output is due solely to increased heart rate.

• Cardiac output remains unchanged due to constant stroke volume.

How is cardiac output calculated?

• Heart rate × stroke volume

• Heart rate + stroke volume

• Heart rate + tidal volume

• Tidal volume × stroke volume

The path taken by blood from the right ventricle to the left ventricle is:

• Right ventricle -> Pulmonary artery -> Lungs -> Pulmonary vein -> Left atrium -> Left ventricle

• Right ventricle -> Aorta -> Body -> Vena cava -> Right atrium -> Left ventricle

• Right ventricle -> Pulmonary vein -> Lungs -> Pulmonary artery -> Left atrium -> Left ventricle

• Right ventricle -> Left atrium -> Lungs -> Pulmonary vein -> Left ventricle

Distinguish how cardiac output, stroke volume and resting heart rate would differ between trained and untrained women during exercise.

• Trained women have higher cardiac output, stroke volume, and lower resting heart rate.

• Untrained women have higher cardiac output, stroke volume, and lower resting heart rate.

• Both trained and untrained women have the same cardiac output, stroke volume, and resting heart rate.

• Trained women have lower cardiac output, stroke volume, and higher resting heart rate.
