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. The pulmonary arteries are unique in that unlike most arteries which carry oxygenated blood to other parts of the body, the pulmonary arteries carry de-oxygenated blood to the lungs. After picking up oxygen, the oxygen rich blood is returned to the heart via the pulmonary veins. 1 of 1.
The right atrium and the right ventricle pump blood into the lungs via the pulmonary artery. The blood picks up oxygen in the lungs and returns to the heart through the left atrium and left ventricle. The left atrium pumps blood through other parts of the heart and the rest of the body. The oxygenated blood circulates through the body. Deoxygenated blood from the body goes back to the right atrium where the process begins again. The aorta and the coronary arteries play an important role in providing oxygenated blood to the rest of the heart. The coronary arteries help move oxygenated blood from the aorta to the heart. The aorta provides oxygenated blood from the left atrium and left ventricle to the rest of the body.
