Etymology
The word 'perfusion' is built on the Latin verb fundere, meaning "to pour". The prefix per-, meaning "through", intensifies this action to convey the idea of "pouring through". In its original Latin form, perfusio described the act of drenching or sprinkling a liquid over something. This literal sense of a liquid being poured through a space was adopted into medical and physiological terminology in the 19th century. It now specifically denotes the vital process by which blood is forced to "pour through" the intricate network of capillaries in bodily tissues, delivering oxygen and nutrients.
