Absolutely 24/7: Our blood makes full circle of body: body-veins>r-heart>lungs>l-heart>entire-body each ~60 seconds resting, faster with exercise. Unlike arterioles rest of body, we adjust constriction of brain arterioles during & between heart beats to partially even out flow to capillaries. The heart is the pump & its output affects entire system split second. See questions: 576482 228427 & tip 918970 more info.
