The geometric organization and control of the microbed varies with different organs and tissue elements. The moment-to-moment regulation of local blood flow occurs without dominant control by the extrinsic nervous system. This enhances the exchange of fluids, solutes and blood gases, and allows rapid redistribution of blood flow during states of stress and high metabolic demand.
微血管的几何结构和调控因不同器官和组织成分而异。局部血流的实时调节在没有外在神经系统主导控制的情况下发生。这增强了液体、溶质和血气的交换，并允许在应激状态和高代谢需求时快速重新分配血流。
