your heart
blood takes oxygen and gives carbon dioxide to the lungs
The pulmonary arteries carry blood from the heart to the lungs and pulmonary veins carry blood back to the heart.
Pulmonary Vein
It is a vessel connectthat connects the heart to the lungs. The pulmonary artery takes blood from the heart to the lungs and the pulmonary vein takes blood from the lungs to the heart. The pulmonary vessels are the only blood vessels in the body after birth that have reversed blood flow. The pulmonary arteries actually carry deoxygenated blood to the lungs and the pulmonary veins carry oxygenated blood to the heart.
Blood travels to the lungs because it is not oxygenated and it will become oxygenated in the lungs, since that is what the lungs are for. The pulmonary artery takes blood to the lungs, and the pulmonary vein takes blood from the lungs back to the heart, from whence it is pumped throughout the body.
The heart pumps the deoxygenated blood trough the right side of it and out trough the pulmonary artery which connects to the lungs.
The pulmonary artery carries deoxygenated blood from the heart to the lungs.
air sacs are in the lungs and when you breathe in blood carries it to the lungs.
The blood passes through tiny capillaries that lie in close proximity to the alveoli in the lungs. This is where the gas exchange takes place.
Pulmonary Artery
Carry oxygenated blood from the lungs to the left atrium so it can be transferred to the aorta which takes the blood to the head and arms.
The pulmonary circulation takes blood from the heart to the lungs and back again. Blood moves from the right ventricle to the pulmonary artery, then into the lungs where blood is oxygenated. Blood returns from the lungs to the heart in the pulmonary vein, and enters the left atrium.
