The common cardinal veins, also known as the ducts of Cuvier, [1] are veins that drain into the sinus venosus during embryonic development. [2] [3] These drain an anterior cardinal vein and a posterior cardinal vein on each side. [2] [3] Each of the ducts of Cuvier receives an ascending vein.
The anterior cardinal veins (precardinal veins) contribute to the formation of the internal jugular veins and together with the common cardinal vein form the superior vena cava. The anastomosis between the two anterior cardinal veins develops into the left brachiocephalic vein .
VV Vitelline veins, UV Umbilical veins, CV Cardinal veins, SV Sinus venosus. The vitelline veins give rise to: [4] Hepatic veins; Inferior portion of Inferior vena cava; Portal vein; Superior mesenteric vein; Inferior mesenteric vein; The branches conveying the blood to the plexus are named the venae advehentes, and become the branches of the ...
The sinus venosus is a large quadrangular cavity which precedes the atrium on the venous side of the chordate heart. [1] [verification needed]In mammals, the sinus venosus exists distinctly only in the embryonic heart where it is found between the two venae cavae; in the adult, the sinus venosus becomes incorporated into the wall of the right atrium to form a smooth part called the sinus ...
In the middle of the fourth week, the sinus venosus receives blood from the three major veins: the vitelline, the umbilical and the common cardinal veins. During the first two months of development, the interatrial septum begins to form. This septum divides the primitive atrium into a right and a left atrium.
Inside the embryo, the dorsal aorta forms and eventually connect the heart to the capillary plexus of the yolk sac. [7] This forms a closed-loop system of rigid endothelial tubing. Even this early in the process of vasculogenesis, before the onset of blood flow, sections of the tube system may express ephrins or neuropilins , genetic markers of ...
The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical cord, heart and systemic blood vessels. A major difference between the fetal circulation and postnatal circulation is that the lungs are not used during the fetal stage resulting in the presence of shunts to move oxygenated blood and ...
