What are the blood vessels of the brain?

Folded arteries system supplies the brain with oxygen that needs to function. Internal carotides and vertebral arteries are the main blood vessels of the brain that supply blood to the brain. These arteries form a circle known as Willis' Circle, named after Thomas Willis, a British doctor who discovered it. The Willis Circle is located at the base of the brain, where other brain vessels are joined. This arterial system is designed so that if there is blocking in one artery, the blood flow can be diverted to other arteries.

Internal carotid arteries provide blood on the front of the brain. The left internal carotide provides blood to the left part of the brain and the right inner carotide provides blood to the right. When each internal carotid artery enters the skull, it is divided into three branches that connect to the anterior cerebral artery, medium brain artery and rear artery.

Front artery provides blood lobes. The front lobes are parts of the brain that control personality, logical meantand voluntary movement. The middle cerebral artery adds blood to parts of the frontal, parietal and time lobes of the brain. This vascular area is associated with sensory and motor activities of the hand, arm, neck and faces and affects speech.

The back of the communicating artery adds blood to time and occipital lobes. The time lobe controls memory, language and auditory processing. Occital lobe controls vision and is responsible for tasks such as engine perception, spatial processing and color discrimination.

vertebral arteries are connected to the basil arteries. This vessel of the brain blood into the brain stem, the back of the brain and part of the brain. Coordinates of the brain stem on the left and right side of the body. The cerebrum is associated with the judgment, perception, decision -making, thought and imagination and brain controls balance and movement.

brain requires constant blood flow to keep its tissues healthy and promote nervous function. It is estimated that the brain uses approximately 25 percent oxygen in the body and almost 20 percent of blood. Unlike other body tissues, the brain cannot store fuel, so it needs a continuous supply of glucose that a constant blood circulation can provide. The blood vessels of the brain circulate blood all over the brain to ensure that all its nerves and cells receive the nutrients they need.
