Which blood vessel carries oxygenated blood to the brain?

Options

A. Cerebral artery
B. Coronoid artery
C. Carotid artery
D. Vertebral artery

Answer

To determine which blood vessel carries oxygenated blood to the brain, we can analyze the options provided:

1. **Cerebral Artery**: This artery is located within the brain and primarily circulates blood within the brain itself. However, it does not carry blood from outside the brain; it distributes blood that has already been supplied to the brain.

2. **Coronary Artery**: This artery is found in the heart and is responsible for supplying oxygenated blood to the heart muscle. It does not supply blood to the brain.

3. **Carotid Artery**: The carotid arteries are located on both sides of the neck and are responsible for transporting oxygenated blood from the heart to the brain. They branch into internal and external carotid arteries, with the internal carotid artery specifically supplying blood to the brain.

4. **Spinal Cord Artery**: This artery supplies blood to the spinal cord and does not directly supply the brain.

Based on this analysis, the correct answer is the **Carotid Artery**, as it is the vessel that carries oxygenated blood to the brain.

**Final Answer**: The blood vessel that carries oxygenated blood to the brain is the **Carotid Artery**.
