Which chamber of the heart pumps blood into the aorta?

The left ventricle is the chamber of the heart responsible for pumping oxygenated blood into the aorta. This chamber has thick muscular walls that allow it to generate the high pressure needed to propel blood throughout the entire body. When the left ventricle contracts, it sends blood into the aorta, the largest artery in the body, from where the blood can then be distributed to all other arteries that supply oxygen and nutrients to tissues and organs.

The other chambers of the heart have distinct roles in the circulatory system. The right atrium receives deoxygenated blood from the body via the superior and inferior vena cavae. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. The right ventricle pumps deoxygenated blood to the lungs via the pulmonary artery for oxygenation. Each of these chambers plays a crucial role in maintaining circulation, but it is specifically the left ventricle that is tasked with delivering blood to the aorta and, subsequently, the rest of the body.
