Sense: adjective/1
All three relate to breathing, but they differ in scope and register. 'Pulmonary' is the formal medical term used in clinical writing, diagnoses, and anatomy — you see it in hospital reports and medical textbooks ('pulmonary fibrosis', 'pulmonary artery'). 'Respiratory' is broader, covering the entire breathing system from the nose down to the alveoli; a 'respiratory infection' could be a common cold, whereas a 'pulmonary infection' specifically affects the lungs. 'Lung' (used attributively) is the everyday English equivalent — native speakers say 'lung cancer' in conversation, not 'pulmonary cancer', and 'lung capacity' in gym class, not 'pulmonary capacity'. Choose 'pulmonary' for technical healthcare contexts, 'respiratory' when discussing the whole breathing system, and 'lung' for general speech.

Etymology
Comes from Latin 'pulmonarius' (meaning 'of the lungs'), which derived from 'pulmo' (lung). The English term was adopted through medical Latin in the 1600s and remains the primary adjective used in anatomy and clinical medicine.
