What part of the hearts electrical conduction system is found in the hearts septum and conveys impulses toward the ventricles?
|
|
SA Node
|
|
|
AV Node
|
|
|
AV Bundle
|
|
|
Purkinje Fibers

Explanation:
Detailed explanation-1: -The electrical impulse travels from the sinus node to the atrioventricular node (also called AV node). There, impulses are slowed down for a very short period, then continue down the conduction pathway via the bundle of His into the ventricles.
Detailed explanation-2: -The atrioventricular (AV) node is a small structure in the heart, located in the Koch triangle, [1] near the coronary sinus on the interatrial septum.
Detailed explanation-3: -In an adult, the sinus node sends out a regular electrical pulse 60 to 100 times per minute. This electrical pulse travels down through the conduction pathways and causes the heart’s lower chambers (ventricles) to contract and pump out blood.
