Yellow circle indicates the left venous angle. 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 ...
In this view, the putative fast and slow pathways toward the AV node (dotted shape in yellow) are depicted. Asterisk (*): central fibrous body, CSO: coronary sinus ostium, ER: Eustachian ridge, ICV: inferior cava vein, OF: oval fossa, STV: septal leaflet of the tricuspid valve, and TT: tendon of Todaro.
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 vessels that remove the deoxygenated blood from the heart muscle are the cardiac veins. These include the great cardiac vein, the middle cardiac vein, the small cardiac vein, the smallest cardiac veins, and the anterior cardiac veins. Cardiac veins carry blood with a poor level of oxygen, from the myocardium to the right atrium.
The right coronary sulcus begins anteriorly and superiorly on the sternocostal surface of the heart. Its position is marked by the location of the right coronary artery , and small cardiac vein . The right coronary sulcus separates the right atrium and its atrial appendage from the right ventricle inferiorly.
The crux cordis or crux of the heart (from Latin "crux" meaning "cross") is the area on the lower back side of the heart where the coronary sulcus (the groove separating the atria from the ventricles) and the posterior interventricular sulcus (the groove separating the left from the right ventricle) meet.

The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization of the internal jugular vein. It can be useful in the differentiation of different forms of heart and lung disease. Classically three upward deflections and two downward deflections have ...
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 ...
