Most of the venous drainage from the equine foot is via veins on the palmar aspect, which generally lack valves. Some small branches of the coronary, subcoronary and bulbar veins have valves. This means that bloodflow from the foot can take different routes and that weightbearing is essential for blood to flow proximally. | Most of the venous drainage from the equine foot is via veins on the palmar aspect, which generally lack valves.
