Innominate Vein, Brachiocephalic Vein

The brachiocephalic vein and innominate vein are important vessels in the circulatory system. They run on each side of the neck and form the superior vena cava, which is one of the largest vessels in the body.

The brachiocephalic vein begins from the subclavian vein and passes through the collarbone, connects with the external jugular vein and forms the superior cava. It plays an important role in transporting blood from the upper body to the heart.

The innominate veins arise from the external jugular vein and pass through the neck, where they join the subclavian veins. They also form the superior cava, which connects them to the brachiocephalic vein. The innominate veins play an important role in transporting blood from the head and neck to the heart.

Both veins are important for human health. Disruption of their work can lead to various diseases, such as thrombosis, inflammation and others. Therefore, it is important to monitor the condition of these vessels and, if necessary, take measures to strengthen them and prevent diseases.



The innominate and brachiocephalic veins are two important veins that run on each side of the neck. They are formed as a result of the fusion of the external jugular and subclavian veins. These veins play an important role in human circulation as they help transport blood from the head and neck to the heart.

The innominate veins pass through the neck and join together to form the superior vena cava, which passes through the chest and drains into the right atrium. The superior vena cava is one of the largest veins in the human body and plays an important role in carrying blood from the upper body to the heart.

The brachiocephalic veins also pass through the neck, but they do not connect to each other. The brachiocephalic veins connect the subclavian veins with the internal jugular vein, which runs along the inner surface of the neck. The brachiocephalic veins help carry blood from the neck and upper torso to the heart.



The innominate vein, also called the “internal azygos vein” or “sigmoid vein,” is an important anatomical element for everyone living on Earth, and this vascular formation is much more common in men than in women. According to statistics, the prevalence of mesentery in the adult population is 60-65%. The system that combines the femoral, subclavian, brachial and internal jugular veins is the internal and external venous branches of the brachiocephalic system. This section directs flowing blood to the brain structures of the head and neck, which allows it to be pumped through the jugular vein into the superior vena cava, left and right atria, and then to the smaller veins of the body, to the general circulatory system, thereby returning functional blood.
