Bloodless → It is formed from "blood" (from Old English "blōd", meaning the red fluid that circulates in the body) and "-less" (meaning without). The word "bloodless" means without blood, often used to describe something that lacks vitality or is devoid of life.
Think of being 'without' ('-less') 'blood' — that's why bloodless means lacking blood.
