Subclavian artery

Verified step by step guidance

Step 1: Begin by identifying the primary function of each vessel listed in the options. For example, arteries are responsible for carrying oxygenated blood away from the heart, while veins return deoxygenated blood to the heart.

Step 2: Focus on the internal carotid artery. Recall that it is a major artery that supplies oxygenated blood directly to the brain, including critical areas such as the cerebral hemispheres and eyes.

Step 3: Examine the facial artery. Understand that this artery primarily supplies blood to the superficial structures of the face, such as the skin and muscles, rather than the brain.

Step 4: Consider the external jugular vein. Note that veins, including the external jugular vein, are responsible for draining blood from the head and neck back to the heart, not supplying blood to the brain.

Step 5: Review the subclavian artery. While it supplies blood to the upper limbs and parts of the neck, it does not directly supply the brain. The internal carotid artery is the correct vessel for brain blood supply.
