Blood flow in a vessel is equal to the pressure gradient across the
length of the vessel (inflow – outflow pressure), divided by the resistance to
flow (Q = ΔP/R). Which ONE of the following statements regarding this
relationship is CORRECT ? (Lecture 5)

Question

Blood flow in a vessel is equal to the pressure gradient across the
length of the vessel (inflow – outflow pressure), divided by the resistance to
flow (Q = ΔP/R). Which  ONE  of the following statements regarding this
relationship is  CORRECT ? (Lecture 5)

Accepted Answer

If outflow pressure is doubled with no change in inflow pressure, flow will be reduced.

Answer

The relationship does not apply to capillaries, as they are so narrow.

Answer

The relationship applies equally to laminar and turbulent flow.

Answer

Flow is increased by increasing the length of the
        vessel.

Answer

Resistance to flow is independent of the diameter of the conducting vessel.
