Through which structure does blood flow after it leaves the right ventricle?

Blood flows from the right ventricle through the pulmonary artery. The right ventricle is responsible for pumping deoxygenated blood into the pulmonary circulation, which is facilitated by the pulmonary artery. This artery branches into the left and right pulmonary arteries, leading to the lungs where the blood will undergo gas exchange—taking in oxygen and releasing carbon dioxide.

After the blood is enriched with oxygen in the lungs, it will return to the heart through the pulmonary veins to the left atrium. From there, it moves to the left ventricle, which then pumps the oxygenated blood into the aorta for distribution to the rest of the body. The mitral valve does not play a role in this process, as it is located between the left atrium and the left ventricle. Understanding this flow sequence is critical for recognizing how the heart functions in circulating blood throughout the body.
