Which of the Following is True of Both the Vertebral

Question

Which of the following is true of both the vertebral and common carotid arteries? Both
A) drain their contents into the jugulars.
B) arise from the subclavian arteries.
C) are branches of the ascending aorta.
D) supply oxygenated blood to the circle of Willis.

Accepted Answer

Both the vertebral and common carotid arteries supply oxygenated blood to the circle of Willis, which is a vital blood supply network providing oxygenated blood to the brain. The other options are incorrect: the vertebral artery drains into the subclavian vein, while the common carotid artery arises directly from the aortic arch, not the subclavian arteries.
