. The development of the human body : a manual of human embryology. Embryology; Embryo, Non-Mammalian. Fig. 137.—Heart of EmbrycTof mm., from a Reconstruction. a, Atrium; ab, aortic bulb; d, dia- phragm; dc, ductus Cuvieri; /, liver; v, ventricle; vj, jugular vein; vu, um- bilical vein.—(His.). Fig. 138.—Heart of Embryo of mm., seen from the Dorsal Surface. DC, Ductus Cuvieri; IA, left atrium rA, right atrium; vf, jugular vein; VI, left ventricle; vu, umbilical vein.— {His.) the heart tube ascends somewhat and then bends so as to pass at first ventrally and then caudally and to the right, where it again bends at first dorsally and then anteriorly to pass over into the aortic bulb. The portion of the curve which lies dorsally and to the left is destined to give rise to both atria, the portion which passes from right to left represents the future left ventricle, while the succeeding portion represents the right ventricle. In later stages (Fig. 138) the left ventricular portion drops downward in front of the atrial.
