The pulmonary trunk carries blood away from which heart chamber?

The pulmonary trunk carries blood away from the right ventricle of the heart. This major blood vessel plays a crucial role in the circulatory system by transporting deoxygenated blood from the right ventricle to the lungs for oxygenation. In the lungs, carbon dioxide is released from the blood, and oxygen is taken up, preparing the blood to be sent back to the heart and distributed throughout the body.

Understanding the anatomy of the heart helps clarify this function: the right ventricle, which receives deoxygenated blood from the right atrium, contracts to pump blood into the pulmonary trunk. From there, the pulmonary trunk divides into the right and left pulmonary arteries, directing blood to each lung. This process is essential for the effective functioning of the cardiovascular system, ensuring that tissues receive oxygen-rich blood after it has been oxygenated in the lungs.
