And these arteries bring deoxynated blood into the lungs. Now, eventually, the pulmonary arteries divide into smaller arteries, and they ultimately divide into these pulmonary arterioles that is shown by number five. And these pulmonary arterioles essentially circle around the alveoli until they connect with the pulmonary capillary. This section shown by number seven. So let's zoom in on this region that contains this capillary section here. So we basically get the following diagram.
