when the left ventricular wall contracts, the mitral valve closes the left atrioventricular orifice, and the blood passes through the aortic valve into the aorta and its branches.
Aotra
Blood flows from the heart into the left atrium, into the left ventricle. From there, it flows from the right artrium into the left ventricle.
When the atria contract, blood flows into the ventricles of the heart. Specifically, the right atrium sends deoxygenated blood into the right ventricle, while the left atrium sends oxygenated blood into the left ventricle. This contraction helps ensure that the ventricles are filled with blood before they contract and pump it out to the lungs and the rest of the body, respectively.
left ventricle
Aotra
The left ventricle receives oxygenated blood from the left atrium. Blood flows from the left atrium through the mitral valve into the left ventricle, which then pumps the blood out into the aorta to supply the body.
No, it flows from the Right Atrium to the Right Ventricle then to the Left Atrium to the Left Ventricle. Hope this helps!
To prevent the back flow of blood into the left and right atrium when the ventricles contract
After taking oxygen from the lungs the blood travels to the left atrium of the heart. From here the blood is pumped to the left ventricle. The left ventricle then pumps the oxygenated blood into the aorta through which it flows to the rest of the body.
The walls of the left atrium contract to force blood through the mitral valve into the left ventricle.
The "beat" of your heart is the contraction of the right and left ventricles. The right atrium passes blood from the body into the right ventricle -- when the ventricle contracts, it forces shut the valve leading back to the atrium, and the blood is pushed into the pulmonary arteries that lead to the lungs. The blood returns from the lungs to the left atrium, and flows into the left ventricle. When the left ventricle contracts, the blood is pushed out of the ventricle into the aorta, the body's main artery, to be carried through the arterial system to the various parts of the body.
From the right ventricle blood flows to the pulmonary artery then to the lung to get oxygenated then to the pulmonary vein into the left auricle to the left ventricle the to the aorta then to the rest of the body.
