2.3 Circulatory and Respiratory Systems

There are three different kinds of blood vessels which carry out the blood from your heart through your body. Arteries are blood vessels that carry blood away from your heart. Arteries are thick-walled and elastic so they are able to withstand the pressure of blood when it is pumped from your heart. Arteries come in different sizes, the biggest being the aorta with a width of 2.5 cm and the smallest being the arterioles with a width of 0.5 mm. Veins, unlike arteries carry deonxygenated blood to your heart where it is pumped into your lungs to be restored with oxygen. Capillaries are tiny blood vessels where oxygen, nutrients and glucose diffuse into the surrounding tissue cells supplying them with energy to carry out their functions.
