CO2 is largely used also because O2 would be a fire hazard in the body. CO2 naturally suppresses any chance of a surgical fire in the body.

I think you are imagining the artery in question to be like a long hose with no where to go and the tab wont shut off. There are offshoots from the artery to smaller vessels ‘arterioles’ and then to the capillary system. The body had a fascinating ability to produce these vessels and essentially redirect that flow as needed.

Also imagine if the tap of the hose is the heart. The vascular system would be a hose with like thousands of other tubes attached to it. If one gets blocked the water just goes to the other tubes. It doesn’t just fill the blocked one up uncontrollably
