Which arteries are responsible for carrying oxygenated blood to the head and neck?

The common carotid arteries are primarily responsible for carrying oxygenated blood to the head and neck. Each common carotid artery branches off into the internal and external carotid arteries. The internal carotid arteries supply blood to the brain and are crucial for adequate cerebral circulation, while the external carotid arteries provide blood to the face and neck structures.

Understanding the role of the common carotid arteries is important for various medical contexts, including surgical procedures and diagnoses related to blood supply and cardiovascular health in the head and neck region. Other arteries listed, such as the subclavian arteries and vertebral arteries, serve different functions in the vascular system. For instance, the subclavian arteries primarily supply blood to the arms and upper body, while the vertebral arteries are responsible for supplying blood to the posterior part of the brain. The brachial arteries primarily serve the arm, making them unrelated to head and neck blood supply. This differentiation helps clarify the specific roles of these arterial structures in the circulatory system.
