The Brachiocephalic Trunk is a major artery that arises from the aortic arch in the human body. It is responsible for supplying blood to the right arm and the head and neck. The trunk quickly divides into two main branches: the right common carotid artery and the right subclavian artery. This artery is significant because it ensures that oxygen-rich blood reaches vital areas, including the brain and upper limbs. Understanding the anatomy and function of the brachiocephalic trunk is important in fields like cardiology and surgery, where vascular health is crucial.
