Root Explanation

Plethysmography → It is formed from "plethysmos" (from Greek, meaning fullness or increase) and "graphia" (from Greek, meaning writing or recording). The word describes the process of measuring changes in volume within an organ or whole body, often used to assess blood flow or lung capacity.

Memory Tip

Think of 'fullness' ('plethysmos') being 'recorded' ('graphia') to understand how much volume is present in a body part.
