Fig. 539. The main arteries and veins of systemic circulation in a human embryo of 7 mm CRL

(about 26 days old).

(After Mall)


From the heart of the bulb of the aorta increases in height and is divided into the aortic arch, which are now the third, fourth and fifth present. Later in the aorta backwards is extensive. Its diameter is much larger in the lumbar region. There they divided into two umbilical arteries. The artery, which in the head area parallel to the aorta runs cranially, the vertebral artery anastomoses with the second segmental artery. Arise on the dorsal circumference of the artery to each side 21 segmental arteries. Fourteen pairs of them occur in the Wolffian body (mesonephros). On the ventral side are two arteries: the A. celiac and A. omphalo-mesenteric (vitelline).

From the veins cardinal veins, the left only shows part of the jugular vein, then the subclavian, the ductus Cuvieri arising from the inferior vena cava cross the liver, the vena omphalo-mesenteric (vitelline) and the umbilical vein.

Fig. 539. Die Hauptarterien und Hauptvenen des Kreislaufes bei einem mensch- lichen Embryo von 7 mm Nackensteifilänge

(etwa 26 Tage alt). (Nach Mall.)


Aus dem Herzen steigt der Bulbus aortae in die Höhe und teilt sich in die Aortenbogen, von denen jetzt der dritte, vierte und fünfte vorhanden sind. Im weiteren Verlauf nach rückwärts wird die Aorta umfangreicher. Ihr Durch- messer ist in der Lendenregion viel größer. Dort teilt sie sich in die zwei Arteriae umbilicales. Die Arterie, welche im Kopfgebiet parallel der Aorta kranialwärts verläuft, ist die Arteria vertebralis, sie anastomosiert mit der zweiten segmentalen Arterie. Auf dem dorsalen Umfang der Arterie entspringen auf jeder Seite 21 Segmentalarterien. Vierzehn Paare davon treten in den Wolff- schen Körper ein. An dem ventralen Umfang gehen zwei Arterien ab: die A. coeliaca und die A. omphalo-mesenterica. Von Venen sind vorhanden die Venae cardinales, die linke nur dargestellt, dann teilweise die Jugularis, die Subclavia sinistra, die Ductus Cuvieri, die sich mit der Vena cava inferior aus der Leber kreuzen, die Vena omphalo-mesenterica und die Vena umbilicalis.
