Veins of lower limb

The veins of the lower extremity are subdivided, like those of the upper, into two sets, superficial and deep; the superficial veins are placed beneath the integument between the two layers of superficial fascia; the deep veins accompany the arteries. Both sets of veins are provided with valves, which are more numerous in the deep than in the superficial set. Valves are also more numerous in the veins of the lower than in those of the upper limb.
