Cardiac conduction system The heartbeat starts in the heart itself due to the sino-atrial node (SAN). The SAN is found in the top of the right atrium and sets the rate at which the heart contracts... The sinoatrial node stimulates the heart. This is what starts the heartbeat. However, the other things listed in the answers also have a part in getting the heart to beat. The previous answer has the correct order of the steps for getting the heart to beat. I'll focus on what the sinoatrial node does. This node is also called the SA Node Conducting System of the Heart. Here's the deal with cardiac muscle cells. They have this inherent capability ( rhythmicity) to contract by themselves unlike skeletal muscle that has to wait for an impulse from a nerve. Cardiac muscle can, if it had to, just contract on its own. It doesn't necessarily need a nerve to tell it to contract Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. The conducting zone of the respiratory system includes the organs and structures not directly involved in gas exchange. The gas exchange occurs in the respiratory zone It generates the force which helps the blood to move through arteries. When blood moves in arteries it causes the contraction and rel .
