Why do dilated vessels drop blood pressure?

Question

Why do dilated vessels drop blood pressure?

Answer 1

The vessels have increased in lumin size but the blood amount is the same, so less force will be excerted onto the walls and therefore less pressure

think of it like a tunnel, the bigger the tunnel water will just trickle out, but the smaller the tunnel and the same amount of water, the water will spurt out at a higher speed, therefore higher pressure
