Task 2

Question 1

Cardiac Output

Answer 1

The amount of blood ejected from either the left or right ventricle each minute.

SV X HR

Normal = 5L/min

Question 2

Stroke Volume

Answer 2

Amount of blood ejected from one ventricle during one contraction.

Calculated by subtracting the amount of blood remaining in the ventricle at the end of systole (ESV) from the amount of blood in the ventricle at the end of diastole (EDV)

Question 3

Cardiac Cycle

Answer 3

Includes all the events in one heart beat.

P Wave to P Wave

Question 4

End Systolic Volume (ESV)

Answer 4

The amount of blood remaining in the ventricle after contraction.

Question 5

End Diastolic Volume (EDV)

Answer 5

The amount of blood in the ventricle at the end of the resting phase.

Question 6

Ventricular Depolarization

Answer 6

Corresponds to the QRS complex on the ECG

Question 7

Dependent Variable

Answer 7

A variable that is observed and measured in an experiment.

Question 8

Independent Variable

Answer 8

An experimental condition that is varied to cause an effect upon the dependent variable.

Question 9

Controlled Variables

Answer 9

Experimental conditions that are kept constant during the experiment.
