During development of the [[veins]], the first indication of a [[parietal]] system consists in the appearance of two short transverse veins, the [[ducts of Cuvier]], which open, one on either side, into the [[sinus venosus]]. Each of these ducts receives an ascending and descending vein. The ascending veins return the blood from the parietes of the trunk and from the [[Wolffian bodies]], and are called '''cardinal veins'''.
