The branch of medicine that deals with diseases of the lungs and breathing system.
From Latin *pulmo, pulmon-* meaning 'lung' and Greek *-logia* meaning 'study of'. It literally means 'the study of the lungs'.
Pulmonology is 'lung science', and its doctors think in terms of air flow the way plumbers think about water flow. Once you spot *pulmo-* for lungs, you’ll recognize it in words like *pulmonary* (lung‑related) and *cardiopulmonary* (heart‑and‑lung).
