Veins have generally been discussed in qualitative, relative terms, as âmore compliant than arteriesâ, subject to âlower pressuresâ. Arteries have thicker walls than veins and contain more smooth muscle tissue and elastin.
Veins need valves to keep blood flowing in one direction because the flow is less constant; the flow in arteries is constant and requires artery walls to be more flexible and strong enough to accommodate the high pressures.The valves in veins allow blood flow in one direction while blocking any counter-flow.
