Development of the vascular bed during embryogenesis in man occurs through loop-like growth of vessels appearing as multiplication, integration, and morphofunctional transformation of vessel loops. Growth of loops provides for the establishment of transport vessels in organs and tissues, and loop integration leads to the establishment of microcirculation with the appearance of connecting and major capillaries, from which true capillaries and capillary networks are formed. Precapillary arterioles and postcapillary venules can be identified topographically in the capillary networks. Formation of blood microcirculation system is complete when morphofunctional arrangement of integrated and nonintegrated loops takes place with the appearance of arterioles and venule collaterals and arterio-venule anastomoses in the vascular network.
人类胚胎发生过程中血管床的发育是通过血管呈环状生长实现的，表现为血管环的增殖、整合以及形态功能转变。血管环的生长为器官和组织中运输血管的建立提供了条件，而血管环的整合则导致微循环的建立，出现连接毛细血管和主要毛细血管，真正的毛细血管和毛细血管网由此形成。在毛细血管网中，可通过拓扑学方法识别毛细血管前微动脉和毛细血管后微静脉。当整合和未整合的血管环在形态功能上进行排列，血管网络中出现小动脉和小静脉侧支以及动静脉吻合时，血液微循环系统的形成即告完成。
