Morphology

plethysmographic = plethysmograph (opaque) = plethysmograph + ic

Etymology

Plethysmographic comes from Greek parts: plethos meaning 'fullness' or 'swelling' (like in plethora) and -graphic meaning 'to record' (like in photograph). So it describes recordings or measurements of changes in volume or 'swelling' in a body part.
