The distribution of cardiac output to each organ is determined by the relative resistance of that organ's vascular bed compared with all other organs.

Question

Quizplus · Accepted Answer

The distribution of cardiac output to each organ is indeed determined by the relative resistance of that organ's vascular bed compared to the vascular beds of all other organs. This is because blood flow to an organ is inversely proportional to the vascular resistance of that organ, according to Ohm's law (Flow = Pressure/Resistance).
