the left ventricle receives blood from the left atrium.
where does the left ventricle recieve blood from?
the left atrium
in an anatomically correct heart the right atrium and right ventricle are working together to supply blood to the pulmonary artery, similarly to how the left atrium and the left ventricle work simultaneously to supply blood to the aorta. during the process of the heart contracting and releasing the right atrium and left atrium contract at the same time, while the left ventricle and right ventricle relax. in opposition, when the left atrium and right atrium are relaxed the left ventricle and right ventricle contract pushing blood to either the aorta or pulmonary artery. in an anatomically correct heart the atria are smaller than the ventricles. the ventricles include more muscle in order to push high quantities of blood throughout the body. normal blood flow throughout the heart begins at the superior vena cava coming from the upper half of the body and the inferior vena cava coming from the lower half of the body. next blood will be in the right atrium and will flow uninterrupted through the tricuspid valve through to the right ventricle. the blood from the right ventricle should go to the pulmonary artery via the pulmonary valve.the blood from the pulmonary vein enters the left atrium, then flows through the mitral valve to the left ventricle. after the left ventricle is filled with blood the aortic valve opens allowing blood to go through, which the blood then enters the aorta and goes to the rest of the body.
crisscross heart
when the left ventricle contracts (systole), pressure rises in the left ventricle. when the pressure in the left ventricle rises above the pressure in the aorta, the aortic valve opens, allowing blood to exit the left ventricle into the aorta. when ventricular systole ends, pressure in the left ventricle rapidly drops. when the pressure in the left ventricle decreases, the momentum of the vortex at the outlet of the valve forces the aortic valve to close. the closure of the aortic valve contributes the a component of the second heart sound (s).
