The subclavian arteries are relatively superficial, and can be seen using ultrasound. [8] Aberrant right subclavian artery is a condition where the right subclavian artery arises on the arch of aorta distal to the left subclavian artery, instead of brachiocephalic trunk. This condition occurs in about 0.4 to 1.8% of the general population.
The thoracic duct drains into the left subclavian vein, [3] 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; the products of fats and lipids can then be carried by the bloodstream to the hepatic ...
The left and right brachiocephalic veins (previously called innominate veins) are major veins in the upper chest, formed by the union of the ipsilateral internal jugular vein and subclavian vein (the so-called venous angle) [1] behind the sternoclavicular joint. [2]

The tunica media may (especially in arteries) be rich in vascular smooth muscle, which controls the caliber of the vessel. Veins do not have the external elastic lamina, but only an internal one. The tunica media is thicker in the arteries rather than the veins. The outer layer is the tunica adventitia and the thickest layer in veins. It is ...
The internal jugular veins join with the subclavian veins more medially to form the brachiocephalic veins. Finally, the left and right brachiocephalic veins join to form the superior vena cava, which delivers deoxygenated blood to the right atrium of the heart. [2] The jugular vein has tributaries consisting of petrosal sinus, facial, lingual ...
The costocervical trunk arises from the upper and back part of the second part of subclavian artery, behind the scalenus anterior on the right side, and medial to that muscle on the left side.
In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb.Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.
