    Blood pressure and peripheral resistance

    Advertisements



    Itīs known that blood pressure doesnīt drop too much along conducting vessels, but it does when fluid reaches arterioles due to the high resistance at that level.
    On the other hand, the following formula states that increased resistance results in increased blood pressure, so that the blood flow remains constant:

    Flow=Pressure/Resistance

    Arenīt these statements contradictory?
    Who can explain?Thank you

    I finally understood what i was asking. Flow=Pressure (difference)/resistance
    An increased resistance produces an increased diference of pressure between the start and the end of the circuit. This increased pressure diference is produced by a drop in the pressure at the arterioles (keeping the pressure at the start of the system constant)
