The ArteriesThe ArteriesCircle of Willis - Circle of Willis - also also
called the cerebral called the cerebral arterial circle this arterial circle this structure surrounds the structure surrounds the pituitary gland and optic pituitary gland and optic chiasma. It connects chiasma. It connects the anterior and the anterior and posterior blood supply posterior blood supply to the brain. It also to the brain. It also equalizes blood pressure equalizes blood pressure in the two brain regions in the two brain regions and provides alternate and provides alternate routes for blood to reach routes for blood to reach the brain tissue in case the brain tissue in case of blockage to the of blockage to the carotid or vertebral carotid or vertebral arteries.arteries.
