Veins Mediastinal Dorsal

The mediastinal dorsal veins (v. mediastinales dorsales), also known as the veins of the base of the lungs, are one of the types of veins that provide blood supply to the lungs and heart. They are part of the body's venous blood system and play an important role in maintaining the health and function of these organs.

The mediastinal dorsal veins begin on the posterior surface of the heart and pass through the chest, where they connect with other veins such as the v. pulmonalis and v. azygos. They then continue their path through the back of the lung and empty into the v. subclavia.

The functions of the dorsal mediastinal veins include the transport of oxygen and nutrients to the lungs, as well as the removal of carbon dioxide and other metabolic products. In addition, they play an important role in regulating body temperature and maintaining normal blood pressure.

Pathology of the mediastinal dorsal veins can be associated with various diseases, such as thrombosis, infection or trauma. In such cases, disruption of blood flow and circulation may occur, which can lead to serious complications, including pulmonary hypoxia and other organ dysfunction.

Thus, the dorsal mediastinal veins are an important component of the venous circulatory system, and their health and functionality are essential for the normal functioning of the lungs and the cardiovascular system as a whole.

***Medio-ventral (retroperitoneal) and spinal (dorsal) veins*** are paired extrapericardial veins located in the anterior mediastinum. Along one of their trunks on the anterior surface of the pericardium, venous blood flows from the upper and middle parts of the pleura into the left atrium, and through the other - into the right. In the veins of the brain, the anterior vertebral plexus is most pronounced, the outflow of venous blood from which occurs along a large longitudinal and
