Detailed explanation-1: -Overview. The Circle of Willis is the joining area of several arteries at the bottom (inferior) side of the brain. At the Circle of Willis, the internal carotid arteries branch into smaller arteries that supply oxygenated blood to over 80% of the cerebrum.
Detailed explanation-2: -The circle of Willis begins to form when the right and left internal carotid artery (ICA) enters the cranial cavity and each one divides into two main branches: the anterior cerebral artery (ACA) and middle cerebral artery (MCA).
Detailed explanation-3: -At the base of the brain, the carotid arteries and vertebral arteries come together to form the Circle of Willis. This is a circle of arteries that pro-vide many paths for blood to supply oxygen and nutrients the brain. From the Circle of Willis, major arteries arise and travel to all parts of the brain.
