A member asked:

Does blood flow from the anterior communicating arteries to the anterior cerebral arteries?

A doctor has provided 1 answer

Not exactly: The flow to the anterior cerebral starts at the heart, goes up the ascending aorta, to carotid arteries which reach the Circle of Willis, and go to anterior cerebral, middle cerebral and posterior cerebral arteries. Anterior communicating can be viewed as a bridging collateral.
