Venous angle

from Wikipedia, the free encyclopedia
Vein angle (circled in yellow)

In anatomy, the vein angle ( angulus venosus ) is the confluence of the two largest veins at the entrance to the breast.

Venous angle of man

As venous angle in humans, the two points (left half of the body right /) are in the blood vessel system referred to, where in each case the internal jugular vein to the subclavian vein (subclavian vein) to the brachiocephalic vein ( Syn. : Innominate vein or Vena innominata combined). This happens retrosternal , directly behind the manubrium sterni . This is also where the large lymphatic strains flow . The left vein angle is the more important one, because here (among others) the thoracic duct flows into the collecting trunk , which transports lymph from the entire lower half of the body; In contrast, only a smaller lymphatic vessel opens into the right vein angle , which carries lymph from the right arm , the right side of the thorax and the right side of the neck ( ductus lymphaticus dexter ). - In the further course, the right and left brachiocephalic veins finally unite to form the (unpaired) superior vena cava (superior vena cava ), which opens into the right atrium .

Venous angles in animal anatomy

In veterinary anatomy, the confluence of the two jugular veins, the external jugular vein and the internal jugular vein, is called the venous angle. If the internal jugular vein is not formed, the confluence of the external jugular vein and subclavian vein is called the venous angle. The lymphatic collecting trunks behave essentially as in humans.
