The left ventricle receives blood from the left atrium of the heart via the mitral valve, also known as the bicuspid valve, or left atrioventricular valve. When it contracts, it pushes the blood volume through the aortic valve and into the aorta.

In comparison with the right ventricle, the left is both shorter in length and is transversely circular in a concave manner. It forms the lesser part of the sternocostal surface of the heart anterosuperiorly, the larger part of the diaphragmatic surface inferiorly as well as the apex of the heart.

Amazing video and it's easy to understand. Would you please make a video on What is Left Ventricular Dysfunction.

It gets blood at less then 80 mm BG since atrial pressure is low after that it undergoes isometric contraction and reaches pressure of 80 then aortic valve opens

Hi.. Can I insert your videos in my Uni project as a references..? Please..

This really help my studies cause I almost grade 6 thank you again cause u make this vid

when the left ventricle contracts the valve will be opened and the valve will be closed

Great video! Thank you. Only one thing I'm struggling to understand. If normal systolic pulmonary artery pressures are between 15 and 30 mmHg then how is it possible that the left heart receives blood at 80 mmHg. Therefore, I would think that the left ventricle receives blood at a pressure of 15 to 30 mmHg from the pulmonary artery. Could you please help me on this? Thanks again for the fantastic video and explanations!
