The arteries are thicker so they can stand up to the huge preassure of blood from the hear, but by the time the blood gets to the veins its a lot slower and have very little.

The arteries are thicker so they can stand up to the huge preassure of blood from the hear, but by the time the blood gets to the veins its a lot slower and have very little. They deliver blood from the capillary beds to the veins.
Blood vessels which carry large quantities of blood, especially blood under high pressure, have thicker walls.
Arteries have more smooth muscle in their walls than veins to accommodate the pulses of blood generated by each contraction of the heart. Right of the bat, veins are superficial so it is much easier to hit a vein than an artery. The arteries are thicker so they can stand up to the huge preassure of blood from the hear, but by the time the blood gets to the veins its a lot slower and have very little.
