Which side of the heart pumps blood to the systemic circuit?

Pumping blood to the body requires generating high arterial pressure, which is the job of the left ventricle. It receives oxygenated blood from the left atrium and ejects it into the aorta, sending it through the systemic arteries to all tissues. The left ventricle’s thick muscular wall reflects this need for strong, forceful contractions to overcome systemic resistance. In contrast, the right ventricle drives blood to the lungs at a much lower pressure via the pulmonary circulation. So, the side that sends blood to the systemic circuit is the left ventricle.
