the left ventricle sends blood to the aorta.
where does the left ventricle send blood to?
aorta
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.

during ventricular contraction, or systole, some of the blood from the left ventricle leaks into the right ventricle, passes through the lungs and reenters the left ventricle via the pulmonary veins and left atrium. this has two net effects. first, the circuitous refluxing of blood causes volume overload on the left ventricle. second, because the left ventricle normally has a much higher systolic pressure (~120 mmhg) than the right ventricle (~20 mmhg), the leakage of blood into the right ventricle therefore elevates right ventricular pressure and volume, causing pulmonary hypertension with its associated symptoms.
