Regarding pulmonary blood flow:

Question

TuteeHUB · Accepted Answer

at the apex Pa>Pv>PA

TuteeHUB · Answer

increased arterial pressure leads to increased pulmonary vascular resistance

TuteeHUB · Answer

localised vasoconstriction is directly due to arterial PO2 hypoxia

TuteeHUB · Answer

regional differences are due to hydrostatic pressure differences

TuteeHUB · Answer

pulmonary arteries and veins have transmural pressures equal to alveolar pressure
