What does the right brachiocephalic vein do?
The primary function of the brachiocephalic veins is to carry deoxygenated blood from the head, neck, arms, and chest back to the heart for oxygenation. Blood from the head drains via the internal jugular veins, while blood from the upper extremities drains via the subclavian veins.
What do the right and left brachiocephalic veins join to make?
The left brachiocephalic vein is nearly always longer than the right. These veins merge to form the superior vena cava, a great vessel, posterior to the junction of the first costal cartilage with the manubrium of the sternum. The brachiocephalic veins are the major veins returning blood to the superior vena cava.
Where do the right and left brachiocephalic veins drain?
At the level of the inferior border of the 1st right costal cartilage, the left and right brachiocephalic veins converge to form the superior vena cava, which goes on to drain into the right atrium of the heart.
What is the function of the brachiocephalic artery?
The brachiocephalic artery, brachiocephalic trunk, or more commonly referred to clinically as the innominate artery, is one of the three great vessels of the aortic arch that supplies blood to the head, neck and upper extremities.
What does the left brachiocephalic vein do?
The left and right brachiocephalic vein join to form the superior vena cava on the right side of the upper chest. These vessels are a vital component of the human circulatory system, aiding in drainage of deoxygenated blood from the head and upper limbs.
Where does the left brachiocephalic vein drain into?
The left brachiocephalic vein crosses posterior to the manubrium to meet the right brachiocephalic vein to form the superior vena cava, which empties into the right atrium (Osborn et al., 1999; Lasjaunias et al., 2001).
What vein drains into the brachiocephalic vein?
