The circle of Willis (also called Willis' circle, loop of Willis, cerebral arterial circle, and Willis polygon) is a circulatory anastomosis that supplies blood to the brain and surrounding structures in reptiles, birds and mammals, including humans.
May 14, 2020 · The circle of Willis is a junction of several important arteries at the bottom part of the brain. It helps blood flow from both the front and back sections of the brain....
Jun 12, 2020 · The circle of Willis is an arterial circle of blood vessels at the base of the brain that connects the left and right internal carotid arteries and the left and right vertebral arteries. It ensures adequate blood flow to the brain when one of the feeding arteries is blocked or narrowed.

Jan 25, 2018 · The Circle of Willis is a network of arteries that are found at the base of the brain and forms the connection between two blood vessels. It provides the blood supply to the mid and forebrain and also regulates the flow of blood in case an artery gets blocked.
Jul 25, 2017 · The circle of Willis is a continuous loop of arteries in the brain that provides collateral circulation. When you turn your head from side-to-side or up and down, the arteries in your neck stretch and flex. In the process, they may become compressed, which restricts blood flow.
The circle of Willis is a circulatory anastomosis that supplies blood to the brain and surrounding structures. Blood flows up to the brain through the vertebral arteries and through the internal carotid arteries.
Jul 5, 2023 · The Circle of Willis is the circular anatomical construct of vessels made up by the internal carotid arteries, the basilar artery, and their intracranial proximal branches. This includes the anterior and posterior communicating arteries and the anterior, middle, and posterior cerebral arteries.
The circle of Willis receives blood from the two main paired arteries that provide blood supply to the head and brain: the carotid arteries anteriorly, and the vertebral arteries posteriorly. This arterial circle is formed by the anastomosis of several arteries, paired and unpaired:
Located at the base of the brain, the Circle of Willis is a ring of anastomotic arteries that preserves the necessary blood flow to the brain if flow in one of its feeding arteries is...
