The pulmonary artery transports blood from the heart to the lungs. While most major arteries branch off from the aorta, the main pulmonary artery extends from the right ventricle of the heart and branches into left and right pulmonary arteries. The left and right pulmonary arteries extend to the left lung and right lungs.
