Which Artery starts the transition to the lungs?
Pulmonary Artery
The pulmonary artery is the artery that starts the transition to the lungs. It is a large blood vessel that arises from the right ventricle of the heart and branches into the left and right pulmonary arteries. These pulmonary arteries carry deoxygenated blood from the heart to the lungs for oxygenation. At the lungs, the pulmonary arteries branch out into smaller blood vessels called arterioles, which then supply the capillary beds where gas exchange occurs between the air and blood. After oxygenation, the blood is returned to the heart via the pulmonary veins.
