ELI5: Explain Like I'm 5

Perfusion

Perfusion is when your body gets all the blood it needs to work the way it's supposed to. Blood is like the gasoline that makes your car go, and your body is like a car that needs to move around to do everything you like to do. Every part of your body needs blood to stay alive, just like your car needs gasoline to run properly. Blood carries important things like oxygen and nutrients that your body needs to stay healthy and strong. Perfusion is all about making sure your body gets enough blood, so it can do everything it's supposed to do.
