The right subclavian artery is a major blood vessel located in the human body that arises from the brachiocephalic trunk, which is a large artery originating from the aortic arch. It is one of the two main branches of the brachiocephalic trunk, the other being the right common carotid artery. The right subclavian artery gets its name from its position beneath the clavicle or collarbone.
The right subclavian artery supplies oxygenated blood to various regions of the body, including the right arm, portions of the chest, shoulders, and upper back. It serves as a vital conduit for delivering oxygen and nutrients to these areas, ensuring their proper functioning.
This artery follows a course beneath the clavicle, then ascends superiorly to travel towards the arm. Along its path, it gives rise to smaller branches, such as the vertebral artery, which supplies blood to the brain, and the internal mammary artery, which provides blood to the chest wall.
Due to its proximity to other structures in the body, the right subclavian artery can sometimes be affected by medical conditions like atherosclerosis or blood clots, leading to reduced blood flow or blockage, which may require medical intervention. Understanding the anatomy and function of the right subclavian artery is crucial in diagnosing and treating potential related conditions.
