Question

Quizplus · Accepted Answer

Stroke volume is the volume of blood ejected from the ventricle during each beat.

Answer:A 
 Systole is the contraction phase of the cardiac cycle.

Answer:B 
 Diastole is the relaxation phase of the cardiac cycle.

Answer:E 
 Cardiac output is the volume of blood pumped by the heart per minute, calculated as the product of stroke volume and heart rate.

Answer:F 
 The sinoatrial node is the natural pacemaker of the heart, located in the right atrium.

Answer:G 
 Purkinje fibers are specialized cardiac muscle fibers located in the ventricles that conduct electrical impulses to the cells of the ventricles, causing them to contract.

Answer:H 
 The P wave is a small, upward deflection on an electrocardiogram (ECG) that represents the depolarization of the atria.

Answer:I 
 The QRS complex is a series of three waves on an ECG that represents the depolarization of the ventricles.

Answer:J 
 The T wave is a small, dome-shaped wave on an ECG that represents the repolarization of the ventricles.
