venous sinus in Medicine Expand. venous sinus n. A cavity at the caudal end of the embryonic cardiac tube in which veins from the intra- and extraembryonic circulatory arcs unite. In adults it develops into the sinuses of the venae cavae.
The venous system is best thought of as two parallel systems, the deep system of veins and the superficial system of veins. These venous systems are connected by hundreds of perforating vessels (each equipped with one way valves) as well as by two larger veins, the Greater Saphenous Vein and the Lesser Saphenous Vein.
