A motorcar engine,for example, needs fuel IN the form of petrol.
It is burnt INSIDE the engine to produce the energy which drives the car.
But petrol,gas,coal,wood or any other form OF fuel can only burn IN the presence of oxygen. Thus, all machines and body cells are alike BY requiring oxygen to burn their fuel and thereby producte the energy needed to perform their functions.
Fuel or nutrients and oxygen are carried IN the blood to all parts of the body.
