The brain is the most complex and vital organ in the human body, controlling both bodily functions and higher-level functions such as language, memory, and decision-making. The brain, on the other hand, relies on an intricate network of blood vessels to supply it with oxygen and nutrients in order to function properly. These blood vessels, known as arteries, are critical to brain health, and any disruption in blood flow can be fatal. The streets on the head are part of the circulatory system, which is in charge of transporting blood throughout the body. These arteries transport blood to the brain and other parts of the head and face. The carotid arteries, which run on either side of the neck, and the vertebral arteries, which run through the spinal column, are the two main arteries in the head. The carotid streets are in charge of supplying blood to the frontal lobe, parietal lobe, and temporal lobe of the brain. The brainstem, cerebellum, and occipital lobe are all supplied with blood by the vertebral arteries. Both sets of streets connect at the base of the brain to form the circle of Willis, which aids in maintaining a constant supply of blood to the brain.
