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
Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
The chance of a deadly heart attack can double due to the combo, the study finds, and several days of excessive heat and humidity alone up chances by 74%. Extreme heat and air pollution doubles ...

In a rare congenital disorder (dextrocardia) the heart is offset to the right side and is felt to be on the left because the left heart is stronger and larger, since it pumps to all body parts. Because the heart is between the lungs, the left lung is smaller than the right lung and has a cardiac notch in its border to accommodate the heart. [8]
The first sign of a malignancy, especially an intra-abdominal one, may be an enlarged Virchow's node, a lymph node in the left supraclavicular area, in the vicinity where the thoracic duct empties into the left brachiocephalic vein, right between where the left subclavian vein and left internal jugular join (i.e., the left Pirogoff angle).
Coronary vessel branches that remain on the surface of the heart and follow the sulci of the heart are called epicardial coronary arteries. [1] The left coronary artery distributes blood to the left side of the heart, the left atrium and ventricle, and the interventricular septum.
