Final answer:
The heart pumps oxygenated blood to all parts of the body except the lungs where gas exchange occurs. This is part of the systemic circulation.
Step-by-step explanation:
Oxygenated blood is pumped by the heart to all parts of the body except where gas exchange occurs in the lungs. The heart consists of four chambers: the left atrium, left ventricle, right atrium, and right ventricle. The left side of the heart receives oxygenated blood from the lungs and pumps it to the rest of the body through the systemic circulation.
