The venous angle (also known as Pirogoff's angle and in Latin as angulus venosus) is the junction where the ipsilateral internal jugular vein and subclavian vein unite to form the ipsilateral brachiocephalic vein. [1] [2] The thoracic duct drains at the left venous angle, and the right lymphatic duct drains at the right
The anatomy of the veins of the heart is very variable, but generally it is formed by the following veins: heart veins that go into the coronary sinus: the great cardiac vein, the middle cardiac vein, the small cardiac vein, the posterior vein of the left ventricle, and the oblique vein of Marshall.
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The heart did not pump blood around, the heart's motion sucked blood in during diastole and the blood moved by the pulsation of the arteries themselves. [93] Galen believed the arterial blood was created by venous blood passing from the left ventricle to the right through 'pores' between the ventricles. [90]
The left and right brachiocephalic veins (previously called innominate veins) are major veins in the upper chest, formed by the union of the ipsilateral internal jugular vein and subclavian vein (the so-called venous angle) [1] behind the sternoclavicular joint. [2]
In over 95% of individuals, the thoracic duct ends by draining either at the venous angle, or into the internal jugular vein, or the subclavian vein, but - in the minority of cases - empties into either the brachiocephalic vein, external jugular vein, suprascapular vein, transverse cervical vein, or vertebral vein. [3]
The coronary sinus receives blood mainly from the small, middle, great, [2] and oblique cardiac veins. It also receives blood from the left marginal vein and the left posterior ventricular vein. [citation needed] Great cardiac vein (run upwards in the anterior interventricular sulcus to the left atrioventricular groove to form the coronary ...
Koch's triangle, also known as the triangle of Koch, is named after the German pathologist Walter Koch. [1] It is an anatomical area located at the base of the right atrium , and its boundaries are the coronary sinus orifice, tendon of Todaro , and the septal leaflet of the right atrioventricular valve (also known as the tricuspid valve).
