The termination of the hepatic veins in the postcava corresponds to the stage shown in schema Fig. 256.
The inter-renal segment of the postcava receives the revehent renal-portal veins.
(b) With hepatic veins and postcava by the ductusvenosus (Figs. 258 and 271).
The postcava now carries the blood from the kidneys directly to the heart.
To the right auricle come three large veins, the right and left prcav and the postcava.
The postcava is well developed, formed by large efferent renal veins.
(b) The ven hepatic revehentes do not empty directly into the sinus venosus, but into the proximal portion of the postcava.
The distal portions of the postcardinal veins form the efferent renal branches and the ascending trunks of the postcava.
The postcava enters the liver in a special prolongation of the liver substance (caval lobe).
