Explain how to flow through a blood vessel is determined.Explain what a “pressure difference†is and why it matters to flow.Define resistance and explain how resistance affects flow. List anddiscuss the 3 factors which influence the resistance throughvessels. For each factor explain the mechanism by which it affectsthe resistance. Which one of these 3 as the largest impact onresistance? Explain why it has the largest impact on flow. Whichone of these 3 can readily be adjusted by the body?
