Deoxygenation blood flows into the right and left lungs through the
Deoxygenated blood flows into the right and left lungs through the pulmonary artery. The heart is a vital organ that pumps blood throughout the body. Deoxygenated blood enters the right atrium of the heart through the superior and inferior vena cava. From there, it passes through the tricuspid valve and into the right ventricle, which then pumps the blood through the pulmonary artery and into the lungs. In the lungs, carbon dioxide is removed from the blood, and oxygen is taken up by the red blood cells. The now oxygenated blood then returns to the heart through the pulmonary veins and enters the left atrium. From there, it passes through the mitral valve and into the left ventricle, which pumps the oxygenated blood out to the rest of the body. So, the pulmonary artery is the blood vessel that carries deoxygenated blood from the heart to the lungs for oxygenation, whereas the pulmonary vein carries oxygenated blood from the lungs to the heart.
