This is wrong, Right? Resistance of Blood Vessel Question.

[The8]

I remember learning specifically that the resistance of arterioles was highest....
am i not right?

Disregard the question. There are so many things wrong from the answer choices to the explanations.

Resistance is inversely proportional to radius^4. That's all you need to know. Resistance to flow in the capillary bed is therefore the greatest.

Pressure drop from arteries to arterioles is the greatest, not resistance.

there are a lot of capillaries though so it adds up in terms of Cross Sectional Area and that actually makes them less resistant from what I read. The arterioles have highest resistance, delta P = CO * Resistance and basically the resistance is what lowers it in the arterioles so the pressure is nice and low for the caps.

No. That is wrong. Where did you read that.
