Remember veins back to the heart. This goes into the heart to deliver oxygen.
The Pulmonary arteries
to the lungs
Blood leaves the pulmonary artery and travels into the lungs. In the lungs the blood releases carbon dioxide and picks up oxygen.
to the lungs
Oxygenated blood from the lungs to the heart. This is unusual as almost all veins carry deoxygenated blood.
The pulmonary vein. Veins go to the heart, arteries come out. Even though the blood is oxygenated, it still travels through a vein to get to the heart. I'll leave it to you to figure out the pulmonary artery.
...to the lungs.
Yes. The pulmonary vein brings oxygenated blood from the lungs into the left atrium of the heart. Once it passes through the bicuspid valve, the left atrium will then pump the blood through the rest of your body.
The systemic arteriole, then the capillaries, the venule, the vein, the vena cava, the heart, the pulmonary artery, the pulmonary arterioles, capillaries, the pulmonary veins, the heart, into the aorta, and back into the artery.

right atrium -> right ventricle -> pulmonary artery -> pulmonary vein -> left atrium -> left ventricle -> aorta
It depends blood doesnt go into the lungs but if your talking about how does blood travel threw lungs its by veins.
