Fig. 573 a, b and c. Plan of the development of the mesonephric portal circulation

a. A vein runs on both sides of the mesonephros, the posterior cardinal laterally and dorsally and the subcardinal medially and ventrally. The posterior cardinal opens cranially into the ductus Cuvieri, while the subcardinal ends blindly. Caudally both veins are connected with the paired v. ischiadica and the unpaired v. caudalis. b. Transverse anastomoses have formed between the posterior cardinal and the subcardinal, traversing the mesonephros. The subcardinal opens into the v. hepatica revehens communis, c. The cardinal has lost its connection with the ductus Cuvieri, but retains that with the vv. ischiadica and caudalis. The subcardinal has retained its opening into the v. hepatica revehens communis, but has lost its connection with the vv. ischiadica and caudalis. Capillary networks have developed in the transverse anastomoses. The blood of the vv. caudalis and ischiadica must now take the following course: 1, v. cardinalis, 2, the transverse anastomoses with capillary networks inside the mesonephros, 3, v. subcardinalis, 4, v. hepatica revehens communis, 5, sinus venosus.
