    Can anyone educate me about the vascular resistance in blood pressure
    What exactly do you want to know? Vascular resistance is defined as the pressure gradient required for a given flow (Resistance = Pressure gradient/Flow). If resistance is high, a greater pressure gradient is required for a given flow. Resistance is proportional to the distance the blood must travel as well as the viscosity of the blood. Resistance is inversely proportional to the radius4 of the vessel. Therefore, if the radius of the vessel is halved, the resistance will increase by a factor of 16 (24=16).
    Resistance = (8 x viscosity x length)/(pi x r4). This is known as Poiseuille's law.
