The heart drives blood directly into the pulmonary trunk and ascending aorta, powering arterial delivery throughout the body.
Systemic veins (via the venae cavae) and pulmonary veins return blood back into the right and left atria of the heart.
The right side of the heart pumps blood to the lungs where gas exchange replenishes oxygen and removes carbon dioxide.
