4. large, muscular blood vessels that deliver blood from the heart to the rest of the body

7. blood vessels that supply the heart muscle with blood containing oxygen and nutrients

12. medical emergency in which blood vessels in the brain become narrow or blocked or burst, disrupting blood flow to a part of the brain
15. disease in which fatty deposits collect in the walls of arteries, restricting blood flow
