Blood traveling through the pulmonary veins is being returned to the heart from the lungs. The pulmonary veins have the distinction of being the only veins in the body which carry oxygenated, rather than deoxygenated blood.
That part of your boday would be your lungs, because it needs to pick up oxygen to go back throught the heart throught the Pulmonary Artery.
Pulmonary means to do with the lungs. A vein leads towards the heart, so it's entering from the lungs and going back to the heart.
Left atrium of the heart.
Veins return to the heart.

Blood traveling through the pulmonary veins is being returned to the heart from the lungs. The pulmonary veins have the distinction of being the only veins in the body which carry oxygenated, rather than deoxygenated blood.
It is being transported to the lungs to be oxygenated, after which it travels to the left side of the heart via the pulmonary veins.
i do NOT KNOW PEOPLES
Dexoygenated blood being brought back to the heart from the body via veins enters the superior or inferior vena cava (largest vein) which empties into the right atrium, it passes through the tricuspid valve into the right ventricle, it then passes through the pulmonary valve into the pulmonary trunk to the left and right pulmonary arteries which carries blood to the left and right lungs where blood picks up oxygen and drops off carbon dioxide, it then returns through the right and left pulmonary veins into the left atrium then it passes through the bicuspid valve into the left ventricle, then passes through the aortic valve into the aorta and back to the rest of the body through arteries

pulmonary artery, where it is then transported to the lungs to pick up oxygen and get rid of carbon dioxide. After circulating through the lungs, the now oxygenated blood returns to the heart through the pulmonary veins before being pumped out to the rest of the body through the aorta.
vains pass through the outer layer of the lung and the oxygen (being soluble) passes through and oxygenates the blood
By definition veins are any blood vessel that return to the heart, as arteries are any blood vessel transporting away from the heart. The Pulmonary Artery and Pulmonary Vein are unique in that virtually all veins carry deoxygenated blood and arteries carry oxygenated blood. These two exceptions however do the opposite. The blood being pumped out by the Left heart receives oxygen rich blood from the lungs only after the Right heart sends all blood returned to the heart through the Pulmonary Artery (carrying deoxygenated blood) to the lungs where the blood is oxygenated and then back to the Left heart through the Pulmonary Vein.
