三、动脉血压的稳定机制人体动脉血压表现有相对稳定性,尤其是平均动脉压(舒张压+1/3脉压)更较稳定。动脉血压的相对隐定是机体稳态的主要表现之一,具有重要的生理意义。动脉血压维持一定水平在于克服外周阻力,维持血流速度,从而保证各器官的血流量。器官血流量与血压成正比,
Third, the stable mechanism of arterial blood pressure Human arterial blood pressure showed a relative stability, especially the average arterial pressure (diastolic blood pressure +1/3 pulse pressure) is more stable. Relatively calm arterial blood pressure is one of the main manifestations of the body’s homeostasis, has important physiological significance. Arterial blood pressure to maintain a certain level is to overcome peripheral resistance, maintain blood flow, thus ensuring the blood flow of various organs. Organ blood flow is proportional to blood pressure,
