Morphology

external + respiration

The meaning is compositionally derived from 'external' (outside) + 'respiration' (breathing), so a learner who knows both words can infer this refers to breathing that occurs at the body/organ level (e.g., lungs) rather than cellular respiration. This straightforward, science-based naming pattern is cross-linguistically common and follows regular English composition, making it transparent to learners who know the constituents.

Etymology

External respiration comes from a simple image: external means 'outside' and respiration means 'breathing'. It refers to the breathing that moves air between the outside and the lungs—bringing in oxygen and sending out carbon dioxide—so it means 'taking in oxygen and getting rid of carbon dioxide'.
