Arteries carry blood from heart to the body.
Walls are thick and muscular to cope with high pressure.
Inner endothelium is folded allowing to strech.
Arteries carry oxygenated blood except pulmonary arties, whcih carry deoxygenated blood.
Form a network around the body.
Blood directed to different areas of demand by muscles in the arterioles which vasodilate or vasoconstrict blood flow.
Take blood to the heart under low pressure.
Wider lumen with very little elastic tissue.
Contains valves to stop blood flowing backwards.
Helped by contraction of body muscles surrounding them.
Carry deoxygenated blood, except for pulmonary veins.
