Final answer:
The left ventricle sends blood to the aorta, which distributes oxygen-rich blood throughout the body. This is part of the systemic circulation which contrasts with the pulmonary circuit handled by the right ventricle.
Step-by-step explanation:
The left ventricle should send blood to the aorta. The left ventricle is the chamber of the heart responsible for pumping oxygenated blood into the systemic circulation. When the left ventricle contracts, it ejects blood through the aortic semilunar valve into the aorta. From the aorta, the blood then branches into smaller arteries and capillaries to supply oxygen-rich blood to the rest of the body.
The right ventricle, on the other hand, is responsible for pumping deoxygenated blood into the pulmonary trunk and then to the lungs for oxygenation. The left and right sides of the heart work together in the cardiac cycle to maintain continuous blood flow through the pulmonary and systemic circuits.
