Venous angle

As venous angle ( venous angle ) is called in the anatomy of the confluence of the two largest veins of the thoracic inlet.

Venous angle of the human

In humans, the confluence of the internal jugular vein with the subclavian subclavian vein to the brachiocephalic vein ( innominate vein Syn ) is called the venous angle at the thoracic inlet behind the clavicle. Here also open the big Lymphsammelstämme. The left venous angle is important because the breast duct ( thoracic duct ) opens as a large lymphatic collecting vessel from the entire lower body here. Right opens only a small lymph vessel from the right arm, the right half of the chest and neck from the right ( right lymphatic duct ). The brachiocephalic veins of both sides unite to unpaired superior vena cava ( superior vena cava ), which opens into the right atrium.

In the English-speaking world the venous angle after Russian surgeon Nikolay Ivanovich Pirogov is sometimes referred to as Pirogov angle.

Venous angle in Animal Anatomy

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