Organ blood flow is determined by perfusion pressure and vasomotor tone in the resistance vessels of the organ. Local factors that regulate vasomotor tone include myogenic and metabolic autoregulation, flow-mediated and conducted responses, and vasoactive substances released from red blood cells. The relative importance of each of these factors varies over time, from tissue to tissue, and among vessel generations.
器官的血流由器官的阻力血管的灌注压和血管舒缩张力决定。调节血管舒缩张力的局部因素包括肌源性和代谢性自身调节、血流介导和传递反应以及红细胞释放的血管活性物质。这些因素中的每一个在时间上、在组织间以及在血管代际间的相对重要性都有所不同。
