WHAT IS CALLED VEINS AND ARTERI ?
Veins and Arteries play major role in our circulator system. When blood leaves the lungs it carries oxygen. The arteries are perceived as carrying oxygenated blood to the tissues under high pressure, while veins carry pressure, while veins carry deoxygenated blood back to the heart. Arteries and arterioles have thicker walls the veins . The smooth muscle that is found in arteries five them extra strength and elasticity to deal with the surges of blood from the heart. Veins "store" blood so much more blood is readily available in your veins.
