Where is the sinoatrial node located?
Right atrium near the entrance of the superior vena cava
Left atrium near the entrance of the pulmonary veins
Right ventricle near the entrance of the pulmonary artery
Left ventricle near the entrance of the aorta
What is the purpose of the delay in the atrioventricular node?
To ensure the atria have ejected all the blood into the ventricles before the ventricles contract
To initiate all heartbeats

ventricular contraction
equivalent to 1 complete heart beat
a heart attack
Explain the role of the cardiac conduction system in the heart.
The cardiac conduction system is responsible for pumping blood through the heart.
The cardiac conduction system only causes irregular heartbeats.
The cardiac conduction system has no role in the heart's electrical activity.
The role of the cardiac conduction system is to coordinate the electrical activity of the heart and ensure that the heart beats in a synchronized and efficient manner.
