Blood vessels

•blood vessels:- Aorta- main artery leaving the heart- Arteries- oxygenated blood to body from heart- Arterioles- Smaller vessel branches - Capillaries- near surface where O2 is released- Venules- smaller vessel between capillaries and veins; starting return of deoxygenated blood- Veins- larger vessels returning deoxygenated blood to heart( Will go to longs for refill)- Superior & inferior vena cava- routes deoxygenated blood back into the atria from the body
