Reply to comment by CardiOMG in How does vasoconstriction reduce blood pressure in haemostasis? by scoliendo

So are all capillary beds fed by more than one artery/arteriole network? Or are some capillary beds only fed by one? And if the latter is the case, what happens to that capillary bed when the blood flow is reduced?

The blood flow doesn’t have to go to 0, just reduced. But also, depending on the part of the body, you don’t need constant circulation. Your legs can go 6-8 hours with no circulation and still survive.
