A morphometric evaluation, utilising a computerised system, was undertaken to quantify the growth of blood vessels in the chick area vasculosa, between the 2nd and the 5th incubation days. In this phase of embryonic growth the total length of the vascular tree for the arterial and venous systems alone, increases more (2.7 times) than the area occupied by the area vasculosa. Two main mechanisms might regulate the growth of vessels: the release of collaterals from the vessels 1.01-2 mm long and the lengthening of the vessels by 2.01-7 mm.
利用计算机系统进行了形态计量学评估，以量化鸡胚绒毛尿囊膜血管在孵化第2天至第5天期间的生长情况。在胚胎生长的这个阶段，仅动脉和静脉系统的血管树总长度增加得更多（2.7倍），超过了绒毛尿囊膜所占的面积。可能有两种主要机制调节血管生长：长度为1.01 - 2毫米的血管分支的释放以及长度为2.01 - 7毫米的血管的延长。
