Learn about the anatomy of the heart and how its chambers, valves, and vessels work together to maintain effective blood circulation throughout the body to sustain life.

Share on Pinterest A diagram of the heart, with the left and right ventricles in the lower section of the heart. How is ejection fraction measured? Generally, your left ventricle is the one ...

Ventricular septal defect is a hole in the wall between the right and left ventricles of the heart. This abnormality usually develops before birth and is found most often in infants.

The semilunar valves stop the back flow of blood into the heart. There is a semilunar valve where the aorta leaves the left ventricle and another where the pulmonary artery leaves the right ventricle.

The S3 heart sound occurs as the mitral valve opens and allows blood to fill the left ventricle passively. The sound happens as a result of blood striking the left ventricle during early diastole.

Double inlet left ventricle (DILV) is a very rare condition in which the heart chambers and valves are malformed. It occurs in about 5-10 of every 100 000 babies born alive. Skip to content ...

In the human heart, the left ventricle is the one that pumps freshly oxygenated blood into the aorta, and from there into the rest of the body. The new lab-grown model could offer researchers a ...
