Fig. 539. Reconstruction of the arterial system of an embryo of 1.38 mm greatest length

with 5-6 pairs of primitive segments. (Embryo Pfannenstiel-Kromer, from the collection of Professor Pfannenstiel.)

The aorta is a continuous vessel with completely closed walls from the level of the second primitive segment forward, from there backwards it is in anlage. On the posterior part of the yolk-sack and on the end-gut is the anlage of the rete peri-intestinale. The a. umbilicalis arises from this rete.
