47
What is the main function of the conduction system of the heart?
To coordinate the contraction of the heart muscle
48
True or False: The conduction system of the heart is responsible for generating the heart's electrical impulses.
True
49
Which part of the heart initiates the electrical impulses in the conduction system?
Sinoatrial (SA) node
50
What is the role of the atrioventricular (AV) node in the conduction system?
To delay the electrical impulses to allow the atria to contract before the ventricles
51
Fill in the blank: The bundle of His branches into the left and right ________.
bundle branches
52
Which part of the conduction system is responsible for transmitting the electrical impulses to the Purkinje fibers?

59
What is the term for an abnormally fast heart rate caused by a dysfunction in the SA node?
Sinus tachycardia
60
What is the significance of the AV node delaying the electrical impulses?
It allows the atria to contract and fill the ventricles with blood before they contract
61
