The interatrial septum is the wall of tissue that separates the right and left atria of the heart. ... In the heart, a ventricle is a heart chamber which collects blood from an atrium (another heart chamber that is smaller than ventricle) and pumps it out of the heart. ... Grays Fig. ... Structure of the Chordae Tendineae Valves like the Tricuspid valve and the Semilunar valves in the heart are attached to the walls of the heart by cord-like tendons called chordae tendineae. ... In anatomy, the papillary muscles of the heart serve to limit the movements of the mitral and tricuspid valves and prevent them from being everted. ... Grays Fig. ... Apex of the Heart: it is the most outer superficial part of the heart which is situated on the left 5th intercostal space. ... The ventricles of the heart are separated by two grooves, one of which, the anterior longitudinal sulcus (or anterior interventricular sulcus), is situated on the sternocostal surface of the heart, close to its left margin. ... The sternocostal surface of the heart (anterior surface of the heart) is directed forward, upward, and to the left. ...

In anatomy, the heart valves are valves in the heart that prevent blood from flowing the wrong way. ... The right ventricle is one of four chambers (two atria and two ventricles) in the human heart. ... In anatomy, the heart valves are valves in the heart that prevent blood from flowing the wrong way. ... The pulmonary arteries carry blood from the heart to the lungs. ... Pulmonary circulation is the portion of the cardiovascular system which carries oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated blood back to the heart. ...

The pulmonary veins carry blood from the lungs to the left atrium of the heart. ... This page is about the muscular organ, the Heart. ... The mitral valve, also known as the bicuspid valve, is a valve in the heart that lies between the left atrium (LA) and the left ventricle (LV). ...
