We've learned that the oxygenated blood leaves the heart at the aorta, goes to the aortic arch, and then to the subclavian artery.
The subclavian artery then splits into some other arteries, and one of them is called the vertebral artery.
The vertebral artery goes right into your spine and then goes up your neck to help give more blood to your brain, along with the internal carotid artery.
