1.	What is meant by origin of heart beats ? Explain the conducting system of heart beats Class 11
Answer» Heartbeat is triggered by electrical impulses which is induced by a specific pathway. The\xa0SA node known as sinoatrial node is\xa0the heart’s natural pacemaker. This impulse begins in this small bundle of specialized cells which is located in the right atrium. The electrical impulse spreads through the walls of the atria and it causes contraction. Contraction sends the blood into the ventricles.
