Why is the cardiovascular system so important to physical fitness?

AllFunctionEssential: Every cell in our body is dependant, (survival & function) on blood flow in a very nearby capillary for supply of o2 + nutrients & removal of co2 + wastes. The cardiovascular system, along with brain coordination of where the blood flow is preferentially sent, via control of arteriolar size/flow control to each bed of capillaries, at any given moment, is the system that enables these functions.
