YOUR BRAIN'S AMAZING BLOOD SUPPLY
BLOOD SUPPLY TO YOUR BRAIN
Your amazing brain requires a rich blood supply in order to function well. Bright red arteries and purple veins flow through your heavily folded grooved mass of grayish-white brain tissue.
Your brain and the blood vessels that connect to it lie completely enclosed inside three layers of membranes called your "meninges."
You will suffer severe permanent brain damage, if your brain is without blood for two to five minutes!
