Name the organ responsible for pumping blood around the human body.
Blood is transported around the body by arteries, capillaries and veins. What is the main function of veins?
to transport oxygenated blood away from the heart
to regulate blood pressure
to filter impurities from the blood
to carry deoxygenated blood back to the heart
Blood is transported around the body by arteries, capillaries and veins. Explain why the structures of arteries and veins are different.
arteries have thinner walls with less smooth muscle and elastic fibers to withstand high pressure from the heart.
veins have thicker walls with more smooth muscle and elastic fibers as they carry blood back to the heart under higher pressure.
veins tend to have valves (but arteries do not) to prevent backflow of blood
pressure is higher in arteries than veins
arteries have thicker walls than veins
