Cardiac Output can be calculated by:

• Heart Rate X Stoke Volume

• Heart Rate X

  Tidal Volume

• Stroke Volume X Tidal Volume

• Tidal Volume X Respiratory Rate

Minute Ventilation can be calculated by:

• Heart Rate X Stoke Volume

• Heart Rate X

  Tidal Volume

• Stroke Volume X Tidal Volume

• Tidal Volume X Respiratory Rate

Heart Rate is:

• The amount of times a heart beats in a minute.

• The amount of times a heart beats.

• The amount of times a heart beats every hour.

• One heart beat.

Stroke Volume is:

• A measure of the amount of blood pumped from the right atrium.

• A measure of the amount of blood pumped from the left atrium.

• A measure of the amount of blood pumped from the right ventricle.

• A measure of the amount of blood pumped from the left ventricle.

Cardiac Output is:

• The amount of blood pumped out of the heart.

• The amount of blood pumped out of the heart per minute.

• The amount of blood pumped around the body.

• The amount of blood pumped out of the heart per hour.

Stroke volume and heart rate both increase during exercise. This results in:

• An increase in tidal volume.

• A decrease in venous return.

• An increase in cardiac output.

• A decrease in blood flow to working muscles

Blood pressure is:

• The pressure recorded during the relaxation phase of the heart cycle.

• The pressure recorded during the contraction phase of the heart cycle. 

• The pressure exerted by the arterial blood against vessel walls as it is forced through the cardiovascular system. 

Systolic blood pressure is:

• The pressure recorded during the relaxation phase of the heart cycle.

• The pressure recorded during the contraction phase of the heart cycle. 

• The pressure exerted by the arterial blood against vessel walls as it is forced through the cardiovascular system. 

Diastolic blood pressure is:

• The pressure recorded during the relaxation phase of the heart cycle.

• The pressure recorded during the contraction phase of the heart cycle. 

• The pressure exerted by the arterial blood against vessel walls as it is forced through the cardiovascular system. 

Arteriovenous oxygen difference (Av02) is:

• A comparison between the concentration of oxygen in the left atrium compared to the oxygen in the left ventricle. 

• A comparison between the concentration of oxygen in the right atrium compared to the oxygen in the right ventricle. 

• A comparison between the concentration of oxygen in the arterial blood (arteries) compared to the oxygen in the venous blood (veins).
