Detailed explanation-1: -The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
Detailed explanation-2: -The left atrium receives blood from the lungs. This blood is rich in oxygen. The left ventricle pumps the blood from the left atrium out to the body, supplying all organs with oxygen-rich blood.
Detailed explanation-3: -Left atrium: one of the four chambers of the heart. The left atrium receives blood full of oxygen from the lungs and then empties the blood into the left ventricle.
Detailed explanation-4: -The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.
Detailed explanation-5: -Location and atrial walls. The cuboidal-shaped left atrium is housed at the base of the heart and is the most posterior of all the cardiac chambers [3].
