The blood is supplied from the heart to the head, neck, and brain primarily through the carotid arteries. There are two main carotid arteries: the left and right. They branch off from the aorta and ascend along the neck, eventually splitting into the internal and external carotid arteries, which deliver oxygenated blood to the brain and facial structures. In addition to the carotid arteries, the vertebral arteries also play a key role in ensuring the brain gets its blood supply. These vessels run through the vertebrae in your neck and combine to form the basilar artery, contributing to the posterior circulation of the brain, which is essential for brainstem and cerebellum function. Together, these pathways form a robust network crucial for maintaining a healthy and well-nourished brain!
