Sense: adjective/1
Respiratory is the standard medical term for anything involving the process of breathing. Breathing is the everyday, non-technical word — you would say 'breathing exercises' in a yoga class, but 'respiratory therapy' in a hospital. Pulmonary is narrower and refers specifically to the lungs themselves: a pulmonary embolism is a blood clot in the lung, whereas a respiratory infection can affect the nose, throat, airways, or lungs. Use respiratory when you want a formal, clinical tone that covers the entire breathing system; use breathing for casual conversation; and use pulmonary only when the lungs alone are the focus.

Etymology
From Latin respirare, made up of re- ('again') and spirare ('to breathe, blow'). The literal sense is 'to breathe again,' which evolved into the modern medical meaning of anything connected with the action of breathing.
