Vascular Arteriolar and venous resistance

Arteriolar and venous resistance do they decrease or increase after load and preload ?

Please give reason for why and why not the opposite ?

Decrease in arteriolar resistance -> increased flow to the periphery -> More blood returns in the Veins -> increased preload / deacreased afterload

Decreased venous resistance -> increased venous pooling of blood -> decreased flow to the heart -> decreased preload.


I hope i'm correct.

You can add decrease after load to you second list as pooling will cause that too.

But the question is which of the above is true?

And if both how to know in which case which one?
