I did B too, but the choice is E !!!
original explanation:
Firstly
there is high flow in the upper extremeties :arrow: excessive blood supply :arrow: vasoconstriction :arrow: increase vascular resistance
Low flow in lower extremeties :arrow: lack of blood supply :arrow: vasodilation for more blood :arrow: decrease vascular resistance
Secondly
By this adaptation mechanism :arrow: blood flow is not very different between upper & lower extremeties
Do you have any different arguments about this explantaion ( from Kaplan)
