Which chamber of the heart pumps oxygenated blood into the aorta?

Left atrium
Right ventricle
Left ventricle
Right atrium

The correct answer is: Left ventricle

The left ventricle is responsible for pumping oxygenated blood into the aorta, which is the body's main artery supplying blood to the systemic circulation. After oxygenation in the lungs, the blood returns to the heart and enters the left atrium. From there, it passes into the left ventricle, which contracts with great force to propel this oxygen-rich blood into the aorta. This high-pressure pumping is crucial for ensuring that oxygenated blood reaches all body tissues efficiently. The aorta then branches off into smaller arteries that distribute blood throughout the different organs and systems in the body. The structure of the left ventricle is adapted for this task, possessing thicker muscular walls than the other heart chambers to generate the necessary pressure for systemic circulation.
