The Circle of Willis is a ring of arteries located at the base of which organ?

Explanation:
The Circle of Willis is located at the base of the brain. It’s a circular network of arteries that connects the internal carotid arteries with the basilar artery, forming a protective ring around the brain’s major vessels. This arrangement helps ensure blood flow to the brain remains stable even if one artery narrows or is blocked. The heart, liver, and lungs do not house this arterial ring; they have their own separate circulation systems, so the base of the brain is the correct location.
