Morphology

body + plethysmograph

This is a transparent noun compound: 'body' (the physical whole) modifies 'plethysmograph' (an instrument measuring volume changes), so the combined meaning — an instrument for measuring body/lung volume — is directly derivable from its parts. The noun+noun composition follows a common cross-linguistic pattern, so a B1 learner who knows both constituents can infer the MWE's meaning.

Etymology

Body plethysmograph is a medical machine whose name gives a clear image: body because the whole person sits inside a box, and plethysmograph because it is a tool that 'records' small changes. So, it means a machine where you sit inside to 'measure' your lungs and breathing.
