Fig. 534. Fetal heart, dorsal half with the afferent paths, open and colored according to the physiological condition of the blood

semi-schematically and enlarged.

(After Boom.)

The heart is shown in diastole. The vena cava. brings venous blood that pours through the atrium into the right ventricle. The inferior vena cava brings blood mixed, so painted red. The blood passes from the inferior vena cava through the foramen ovale into the left atrium, then left the chamber. The left atrium receives venous blood still through the pulmonary veins. White arrows indicate the flow direction.

Fig. 534. Fetales Herz, dorsale Hälfte mit den zuführenden Bahnen , geöffnet

und entsprechend der physiologischen Beschaffenheit des Blutes koloriert. Halb- schematisch und vergrößert.

(Nach Bumm.)

Das Herz ist in der Diastole dargestellt. Die Vena cava sup. bringt venöses Blut, das sich durch den Vorhof in die rechte Kammer ergießt. Die Vena cava inferior bringt gemischtes Blut, deshalb rot bemalt. Das Blut gelangt von der Vena cava inferior durch das Foramen ovale in den linken Vor- hof, dann in die linke Kammer. Der linke Vorhof erhält noch venöses Blut durch die Lungenvenen. Weiße Pfeile deuten auf die Stromrichtung.
