Answer:
The septum of the heart is a wall of tissue that separates the left and right sides of the heart. It consists of the atrial septum and the ventricular septum. The atrial septum separates the left and right atria, while the ventricular septum separates the left and right ventricles.
The heart's septum has three parts: the atrial septum, the atrioventricular septum, and the ventricular septum
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.
A pacemaker is a small device that's placed (implanted) in the chest to help control the heartbeat. It's used to prevent the heart from beating too slowly. Implanting a pacemaker in the chest requires a surgical procedure. A pacemaker is also called a cardiac pacing device.
The left ventricle is the thickest of the heart's chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.
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 four heart valves, which keep blood flowing in the right direction, are the mitral, tricuspid, pulmonary and aortic valves. Each valve has flaps (leaflets) that open and close once per heartbeat.
Tricuspid Valve. Has three leaflets or cusps. ...
Pulmonary Valve (or Pulmonic Valve) (link opens in new window) ...
Mitral Valve. Has two leaflets. ...
Aortic Valve. Has three leaflets, unless it's abnormal from birth, i.e., bicuspid aortic valve
