Sinoatrial node is the impulse-generating tissue located in which chamber of the heart?

Explanation:
The heart’s natural pacemaker, the sinoatrial node, is located in the wall of the right atrium near where the superior vena cava enters. Its pacemaker cells have automaticity, creating the electrical impulse that starts each heartbeat and sets the heart rate. From there, the impulse spreads through the atria and onward to the ventricles via the conduction system. The left atrium and the ventricles do not house the sinoatrial node, which is why they’re not correct locations for the impulse-generating tissue.
