R = Resistance of blood vessel. Blood flows from area of high pressure to an area of low pressure, down the pressure gradient. When heart contracts, it gives pressure to the blood, which is main driving force for flow through a vessel.Due to resistance in the vessel, the pressure drops as blood flows. = Resistance of blood vessel.
