Fig. 463. Heart of human embryo of about fifteen days

Reconstruction by Wilhelm His (1831-1904)

The sinus venosus is at first situated in the septum transversum (a layer of mesoderm in which the liver and the central tendon of the diaphragm are developed) behind the primitive atrium, and is formed by the union of the vitelline veins. The veins or ducts of Cuvier from the body of the embryo and the umbilical veins from the placenta subsequently open into it (Fig. 463) . The sinus is at first place transversely, and opens by a median aperture into the primitive atrium.
