Question

Quizplus · Accepted Answer

The Purkinje fiber is the last structure in the heart conduction system and stimulates the ventricles to contract.

Answer: A
 Systole is the phase of the cardiac cycle where the heart muscles contract, leading to blood ejection.

Answer: B
 Diastole is the phase of the cardiac cycle where the heart muscles relax and fill with blood.

Answer: C
 The cardiac cycle is the complete sequence of events in one heartbeat, including systole and diastole.

Answer: D
 Stroke volume is the amount of blood ejected by the heart in each contraction.

Answer: E
 Cardiac output is the amount of blood pumped by the heart per unit of time.

Answer: F
 The sinoatrial node is a group of cells in the right atrium that initiates the heartbeat.

Answer: H
 The P wave is a small upward deflection in the electrocardiogram that represents atrial depolarization.

Answer: I
 The QRS complex is a series of deflections in the electrocardiogram that represent ventricular depolarization.

Answer: J
 The T wave is a small upward deflection in the electrocardiogram that represents ventricular repolarization.
