postcava

(b) With hepatic veins and postcava by the ductusvenosus (Figs. 258 and 271).

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.

The postcava now carries the blood from the kidneys directly to the heart.

(b) The ven hepatic revehentes do not empty directly into the sinus venosus, but into the proximal portion of the postcava.
