Which structure in the heart pumps oxygenated blood to the body?

The left ventricle is responsible for pumping oxygenated blood from the heart to the rest of the body. After blood is oxygenated in the lungs, it returns to the heart and enters the left atrium. From there, blood flows into the left ventricle, which has muscular walls that contract powerfully. This contraction propels the blood through the aorta, the largest artery in the body, allowing it to circulate throughout various tissues and organs where it releases oxygen and gathers carbon dioxide.

Understanding the role of the left ventricle is crucial, as it is adapted for this function with thicker muscular walls compared to the other chambers of the heart. Its primary purpose is to generate sufficient force to overcome systemic resistance and ensure that oxygenated blood is delivered effectively to all parts of the body.
