Blood flows from the right ventricle to the pulmonary arteries and then to the lobar arteries. From there, the blood flows through capillary beds, where gas exchange occurs, and then drains into lobar veins. The lobar veins converge into pulmonary veins, which carry oxygenated blood back to the left atrium. Finally, the blood travels through the left atrium to reach the left ventricle, which pumps it out to the rest of the body via the systemic circulation.
