Is it true that the blood flow rate through every blood vessel per minute is constant?

No. Blood flow rates through blood vessels are not constant per minute; rather, they fluctuate dynamically due to physiological autoregulation, vasomotor tone changes, and pulsatile cardiac activity. Evidence demonstrates that regional blood flow actively adapts to metabolic needs, pressure changes, and pharmacological interventions.

The analysis

The claim states that the blood flow rate through every blood vessel per minute is constant. Physiological principles and the provided literature (such as papers 0, 1, and 7) establish that blood flow is inherently pulsatile, regionally variable, and dynamically regulated through mechanisms like autoregulation and vasomotor tone changes. Therefore, the claim is directly refuted by established cardiovascular physiology.
