Related to venous pump: venous plexus foot pump
venous pump; muscle pump contraction of muscle tissue surrounding a lower-limb vein (compartmented by valves), allowing venous return against gravity
venous foot pump facilitation of venous return from deep plantar veins into distal part of lower leg by contraction of (proximal) plantar intrinsic foot muscles and plantar fascia tension; plantar fascia tension is maximal at toe off (when foot is in supination); venous blood moves proximally from foot into lower limb during each foot step, at heel strike and again at toe off
venous leg pump; calf pump facilitation of venous blood movement within deep lower-leg veins by gastrocnemius and soleus contraction; overlying muscle mass contraction/relaxation during gait applies intermittent pressure to deep veins causing blood to move proximally, up through valved segments within deep veins of lower leg
