The pacemaker of the heart is known as the atrioventricular node.
A) True
B) False

That’s actually false! The pacemaker of the heart is the sinoatrial (SA) node, located in the right atrium. It generates electrical impulses that regulate the heartbeat, making it the primary conductor of cardiac rhythm. The atrioventricular (AV) node is important too, but it serves as a relay station that slows down the electrical signal before it moves to the ventricles.

If you’ve ever wondered how the heart stays in sync, think of the SA node as the conductor of an orchestra, ensuring that all instruments (or heart chambers) come in at the right time to create a beautiful symphony of rhythm and beat!
