Root Explanation

Plethysmogram → It is formed from "plethysmos" (Greek, meaning fullness or increase) and "gramma" (Greek, meaning something written or recorded). The word "plethysmogram" refers to a record or measurement of the fullness or volume of a part of the body, typically used in medical contexts.

Memory Tip

Think of 'fullness' ('plethysmos') being 'recorded' ('gramma') — that's why a plethysmogram measures the fullness of blood flow in a specific area.
