How does vasodilation work?

Obviously it means it dilates your veins. Makes them larger in diameter.
What secondary effects does this have on the body? For instance does taking a vasodilator effectively lower blood pressure? I imagine if your veins are dilated they have more actual physical space in them, meaning yea your blood pressure gunna drop right cuz you didnt actually fill that extra space with extra blood did you? Or shit I guess your body has to fill that extra space with blood.. So does vasodilating cause your body to quickly make more blood? Leaving you with a higher blood pressure once the dilation recedes? Or is blood pressure so well regulated that it isnt even really a concern in regards to vasodilators?
How bout other shit like does it put extra surface tension on the walls of your veins? Like putting more air in a ballon increases surface tension on the balloon walls right? Or is this sorta negated by the lowered blood pressure? Assuming Im correct in thinking blood pressure reduces as vasodilation increases?
Any effect on blood viscosity, etc...?
Basically just trying to understand vasodilation more in depth, more than just what it means as a word.
Thanks.

I think vasodilators like niacin mostly are beneficial because they help improve the elasticity of arteries/veins making it easier for them to compensate for change? That was my understanding of them anyway.

Vasodialators are muscle relaxants for the muscles that surround arteries and veins. Blood pressure in veins is much lower than the arteries, and veins are more flexible. Blood volume changes slowly and the body compensates by changing the diameter of the vessels and by moving water in and out of the blood. You can have vasoconstriction of the small vessels in the extremities with vasodilation in the larger arteries. (This Happens in stressful situations and With many drugs.)
