How many chambers does the heart have

You are here Home » How the Heart Works. Top of the page. Topic Overview The heart is at the center of your circulatory system, which is a network of blood vessels that delivers blood to every part of your body. Your heart is a muscle, and its job is to pump blood throughout your circulatory system. How does my heart pump blood? Your heart is divided into two separate pumping systems, the right side and the left side.

The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body. How does blood flow through the heart? Blood flows through your heart and lungs in four steps: The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve.

The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body. How does my heart maintain its normal function? To do this, your heart needs to: Regulate the timing of your heartbeat. Your heart's electrical system controls the timing of the pump.

The electrical system keeps your heart beating in a regular rhythm and adjusts the rate at which it beats. When the electrical system is working properly, it maintains a normal heart rate and rhythm.

Problems with this electrical system can cause an arrhythmia, which means that your heart chambers are beating in an uncoordinated or random way or that your heart is beating too fast tachycardia or too slow bradycardia. Keep your heart muscle healthy. The four chambers of your heart are made of a special type of muscle called myocardium. Main Content. Important Phone Numbers. Top of the page. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.

The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the oxygen-rich blood to the body. The two upper chambers are called the atria. The right atrium and left atrium are separated by a wall of tissue called the atrial septum. The two lower chambers are called the ventricles, and are separated into the right and left ventricle by the ventricular septum. The ventricles have thicker walls and pump blood to the lungs and body.

The bundle branches are a part of the electrical system of the heart. The electrical system controls the heartbeat and….
