Where are the subclavian veins and what is their function?
The subclavian vein (SVC) is classified as a deep vein and is the major venous channel that drains the upper extremities. Other deep veins of the upper extremity that accompany the major arteries include the radial, ulnar, brachial, axillary veins.
What happens if the subclavian vein is blocked?
This tissue causes the vein to narrow and restrict blood flow, leading to the formation of blood clots. Left untreated, axillo-subclavian vein thrombosis can cause: Arm pain and fatigue. Arm swelling.
What do the subclavian veins drain into?
The subclavian vein is a paired large vein, one on either side of the body, that is responsible for draining blood from the upper extremities, allowing this blood to return to the heart….

Does the subclavian vein carry oxygenated blood?
There are two subclavian arteries, which supply oxygen-rich blood to each side of the body. The subclavian arteries also provide oxygenated blood to the back of the cerebrum (the largest part of the brain), the neck and upper limbs, as well as the superior (upper region) and anterior (front area) of the chest wall.
What is the main function of subclavian artery?
The subclavian arteries lie just below the clavicles, providing blood supply to the bilateral upper extremities with contributions to the head and neck. The right subclavian artery derives from the brachiocephalic trunk, while the left subclavian artery originates directly from the aortic arch.
What is meant by subclavian vein?
Medical Definition of subclavian vein : the proximal part of the main vein of the arm that is a continuation of the axillary vein and extends from the level of the first rib to the sternal end of the clavicle where it unites with the internal jugular vein to form the brachiocephalic vein.
Is the subclavian vein a deep vein?
In the upper extremity the deep veins include the paired radial veins, paired ulnar veins, paired brachial veins, axillary vein, and subclavian vein.
Is subclavian vein thrombosis serious?
Subclavian vein thrombosis (SCVT) is a condition where a blood clot forms in the subclavian vein. SCVT can occur from multiple etiologies and is a potentially life-threatening pathology if not treated in a timely manner.
Is subclavian vein a deep vein?
What is the function of subclavian artery?
What type of artery is subclavian?
The subclavian arteries are asymmetric paired arteries that supply blood to the posterior cerebrum, cerebellum, posterior neck, upper limbs and the superior and anterior chest wall.
What system is the subclavian artery part of?
The left subclavian artery is the fifth branch of the aorta and the third branch from the arch of the aorta. The right subclavian artery arises from the brachiocephalic artery and its branches.
What vessel drains into the subclavian vein?
Function. The thoracic duct drains into the left subclavian vein, near its junction with the left internal jugular vein. It carries lymph (water and solutes) from the lymphatic system, as well as chylomicrons or chyle, formed in the intestines from dietary fat and lipids, allowing these to enter the bloodstream;
What is jugular vein and its functions?
Jugular vein, any of several veins of the neck that drain blood from the brain, face, and neck, returning it to the heart via the superior vena cava. The main vessels are the external jugular vein and the interior jugular vein. The external jugular vein receives blood from the neck, the outside of the cranium, and the deep tissues of the face and empties into the subclavian veins (continuations of the principal veins of the arms or forelimbs).
What is the function of jugular vein?
The jugular veins play an important role in the venous drainage of the head and the neck. Located besides the common carotid artery in the neck, the internal jugular veins are primarily responsible for carrying deoxygenated blood from the brain, as well as superficial parts of the face and the neck to the heart.
What vein is formed by the Union of the radial and ulnar veins?
Each brachial vein begins at the elbow, where the radial veins and ulnar veins combine to form the brachial artery. They end under the shoulder blade, at the teres major muscle, where they merge with the basilic vein.
