The arterial supply to the digit and fetlock of the thoracic limb comes mainly from the '''median palmar artery'''. The median palmar artery divides in the distal fourth of the [[Limb Bones and Cartilages - Horse Anatomy#Metacarpals and Metatarsals|metacarpus]] between the[[Tendons - Horse Anatomy#Flexors|superficial and deep digital flexor tendons]] and the [[Tendons - Horse Anatomy#Flexors|suspensory ligament]], to become the '''medial and lateral digital arteries'''. Part of the '''deep palmar arch''' anastamoses with the '''lateral digital artery''' to form the '''superficial palmar arch''', which supplies the [[Joints and Ligaments - Horse Anatomy#Metacarpophalangeal (Fetlock) Joint|fetlock joint]].

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 blood flow from the foot can take different routes and that weightbearing is essential for blood to flow proximally.
