Perfusion

Definition

The passage of blood through the circulatory system to organs and tissues. Essentially, whether your body parts are getting their scheduled deliveries of oxygen and nutrients.

Example Usage

The surgeon checked capillary perfusion in the reattached finger by pressing the nail bed and watching it pink up, playing a high-stakes game of 'does it work?'

Origin

From Latin 'perfusio,' meaning 'a pouring over'

Fun Fact

Poor perfusion gives you that 'pins and needles' feeling when your leg falls asleep, which is your nerves literally screaming about their delivery delays.
