Dorsal digital arteries of the foot
In the foot, the dorsal digital arteries of the foot supply blood to the toes. The arteries carry oxygenated blood to these toes. There are collateral digital branches of the dorsal metatarsal arteries in the foot. These also occur in the hand, but unlike the palmar arteries, the dorsal digital arteries do no reach the distal digit. The dorsal digital arteries of the foot carry blood from the heart to the toes. These arteries are flexible and elastic, made of three layers that include on layer that is muscular. The muscular layer works to contract the artery in rhythm, helping to pump the blood in the body. The dorsal digital arteries of the foot are susceptible to the clogging of the arteries or buildup of fat in the arteries that can lead to atherosclerosis. The clogging or buildup of fat in the dorsal digital arteries of the foot can cause a loss of circulation to the area of the toes in the feet.
