Essentially your entire body speeds up and runs hotter (just like a car). Your heart, your muscles and most organs work harder and faster (thus requiring more engery - burning more calories). Because you are running hotter you sweat and unlike a car your raditor (cooling system - blood vessels) loses fluid and you need to drink water or a sports drink with some sodium and potassium (if these get too out of balance it can effect your heart rythym and cause major problems). There are many other things going on in the body at the same time but hopefully you were looking for the exercise-effect type of answer.
