Blood Flow And Pressure Flashcards
What affect will increasing the pressure in an artery have on the pressure and flow of flow in the arteriole downstream?
It will increase pressure and flow in the arteriole
How will vasoconstriction to increase venous return impact on pressure in upstream vessels?
It will increase pressure in upstream vessels
How will the dilation or constriction of a single arteriole affect the overall arteriole pressure and the blood flow to the area which that single arteriole supplies?
The overall arteriole pressure will be unaffected as cardiac output will be increased so as to maintain this pressure
However, blood flow to the particular area which that arteriole supplies will be increased or decreased accordingly
How will the dilation of arterioles with a constant mean arterial blood pressure affect permeabilising of the capillary wall?
It will increase permeability of the capillary wall
The constriction of arterioles in one part of the body diverts blood flow to other parts. T/F?
False
