Pulmonary blood vessel

**Pulmonary blood vessels** comprise the pulmonary arteries, capillaries, and veins responsible for transporting blood between the heart and lungs[1][7][8]. The pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs, where gas exchange occurs in the alveolar capillary network; the pulmonary veins return oxygenated blood from the lungs to the left atrium[1][3][5][7][8]. This specialized vascular network supports oxygen uptake and carbon dioxide removal and is involved in the pathophysiology of conditions such as pulmonary hypertension, embolism, and various heart and lung diseases[1][4][7]. As a vascular bed and not an individual molecular target, therapeutic modulation addresses components of the vessel wall (e.g., smooth muscle or endothelium) rather than the vessel as a whole. **Note:** "Pulmonary blood vessels" describes an anatomical/physiological system, not a specific molecule, receptor, gene, or canonical drug target. For structured biochemical or pharmacological data, queries must specify particular molecular targets within the pulmonary vasculature, such as "endothelin receptor type A," "pulmonary arterial smooth muscle potassium channel," or "vascular endothelial growth factor receptor."
