How do veins and arteries bend/twist without blood getting stopped or clogged?

When a water hose is bent far enough, the flow of water through it is choked and very little water comes out. When we bend our arms or move our legs, shouldnt the same thing happen?

Arteries are sturdier than you think. Thick walled and flexible, arteries can withstand a good amount of compression. As per veins, there is enough collateral circulation that if one gets compressed, the rest of the venous system can compensate.
