Vienna Regional Radial

The marginal radial vein is one of the important anatomical structures in the human body. It plays an important role in blood circulation and blood supply to various tissues and organs. In addition, the marginal radial vein is of great importance in the diagnosis and treatment of various diseases. In this article we will take a closer look at the marginal radial vein and its role in the human body.

The marginal radial vein is one of the three main tributaries of the human circulatory system. It collects blood from the periphery and transfers it to the main systemic channel. Thus, the marginal venous arterial vein is a connecting channel that connects arteries and veins. In the human body, there are several tributaries of the marginal radial vein, such as the armpit, interthoracic cavity and other areas. Each of them has its own name and performs its own specific function. But the most important part of the peripheral radial vein system is the terminal part, which is located in the area of ​​the palm and fingers. Ultimately, blood from the edges of the arm flows to the back of the wrist, from where it enters the marginal radial vein and then into the central trunk of the bloodstream. One of the important functions of the marginal Radial Vein is the separation of blood. The marginal venous arterial venous system can be divided into several branches of various sizes and shapes. For example, on the back of the hand the edges may be distinguished into two or three crowns, and on the forearm there is a large branch that distributes the blood. Each branch has its own unique function, for example, one of the branches may be responsible for supplying oxygen to skin cells, another for transporting nutrients to the joints, and the third for nourishing muscles. Inside the system of the marginal Venalradial Venous artery, the process of exchange filtration occurs - the process of filtering plasma through capillaries, the walls of which have high permeability. It is thanks to this process - filtering - that nutrition is transferred from one organ or system to another. This also explains why, in most cases when the marginal venous arterial vein is damaged,

**Marginal radial vein** - the lateral branch of the saphenous vein of the hand, departs from the medial half of the saphenous vein of the forearm in the anatomical snuffbox, in the position of flexion of the wrist joint 90 °. The veins of the shoulder (1.5–3 Knützspiel units) without branches are part of the marginal branch, reach the border of the middle and distal thirds of the forearm and end in the wide subcutaneous groove of the lower third of the forearm on the side of the pectoralis major muscle.

The diameter of the marginal radial vein is usually no more than 6 mm, length - 4–8 cm

The marginal radial vein (lat. vena marginalis radi, “lines”) is an anatomical branch of the external genital vein, which carries blood from the urethra to the lower limb.

Physiology of veins and lymphovenous bed. The most physiological mechanism of venous outflow from the lower extremities is considered to be the reverse movement of venous blood through the system of saphenous veins of the proximal superior pudendal vein and further through the system of communicating veins. These large and major vessels drain blood from the deep veins of the pelvis and lower extremities to the superior tributaries of the internal jugular vein (Figure). If the described mechanism functioned normally, blood would enter the venous system not only from the abdominal cavity through the prevesical vein, but also from the pelvic and superficial veins through the internal pudendal vein. Internal connections between the arterial and venous blood supply would ultimately provide blood supply to the entire body from the neck to the back of the head. The functioning of this mechanism, however, is only possible with normal patency of the deep veins of both lower extremities
