Pulmonary artery
A bronchus is shown in longitudinal section with its accompanying pulmonary artery. Pulmonary arteries travel alongside respiratory passageways conveying deoxygenated blood to the alveolar capillaries. Pulmonary arteries branch together with their adjacent respiratory passageways, decreasing in size as they approach the alveoli. 100x
