  • Structure of Human Blood Vessels
    • Blood vessels: tubes that transport blood from one part of human body to another
    • Arteries: blood vessels that carry blood away from the heart
      • Branch out into smaller vessels: arterioles
        • Arterioles branch to form tiny vessels with thin walls: capillaries.
    • Capillaries: sites for the exchange of respiratory gases, nutrients and wastes
      • Join with one another to form venules.
    • Veins transport blood back to the heart
