Subclavian artery Anatomy : Origin, Course, Parts, Branches, Relations and Clinical anatomy
Branches of the Subclavian Artery
------------------------------------------------------
The left and right subclavian arteries are located in the thorax (chest) underneath the clavicles (commonly known as the collarbones). The left subclavian artery receives oxygenated blood from the aortic arch (the top portion of the largest artery in the body that carries blood away from the heart). The right subclavian artery receives blood from the brachiocephalic branch.
The Left Subclavian Artery
------------------------------------------
Branches off directly from the arch of the aorta (as it travels down to supply oxygenated blood to the upper body)
Passes between the anterior and middle scalene muscles (located in the neck)
Ends at the outer border of the first rib where it becomes the axillary artery, which supplies blood to the axillary (armpit area) region of the body. The axillary artery continues down the arm to become the ulnar and radial arteries (supplying oxygenated blood to the arm).
The Right Subclavian Artery
---------------------------------------------
Arises from the brachiocephalic trunk (the second branch to arise from the aorta)
Travels posteriorly (behind) the sternoclavicular joint (the area where the clavicle [collarbone] and the sternum [breastbone] come together).
Becomes the axillary artery once it passes the first rib. The axillary artery supplies blood to the axillary region of the body; it extends down the arm to become the ulnar and radial arteries (supplying oxygenated blood to the arm).
