Pulmonary capillaries
Deoxygenated blood from the pulmonary arteries supplies the pulmonary capillaries in the interalveolar septa. The walls of these capillaries form a portion of the air-blood barrier, across which oxygen and carbon dioxide are transported. Pulmonary capillaries drain into pulmonary veins. 1000x
