On the dorsum of the foot the dorsal digital veins receive, in the clefts between the toes, the intercapitular veins from the plantar venous arch and join to form short common digital veins which unite across the distal ends of the metatarsal bones in a dorsal venous arch.
The foot is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws or nails.
On the dorsum of the foot the dorsal digital veins receive, in the clefts between the toes, the intercapitular veins from the plantar venous arch and join to form short common digital veins.
The four plantar metatarsal veins run backward in the metatarsal spaces, communicate, by means of perforating veins, with the veins on the dorsum of the foot, and unite to form the plantar venous arch which lies alongside the plantar arterial arch.
The great saphenous vein is a large, subcutaneous, superficial vein of the leg. It is the longest vein in the body, running along the length of the lower limb, returning blood from the foot, leg and thigh to the deep femoral vein at the femoral triangle.
The azygos vein is a vein running up the side of the thoracic vertebral column draining itself towards the superior vena cava. It connects the systems of superior vena cava and inferior vena cava and can provide an alternative path for blood to the right atrium when either of the venae cavae is blocked.
The dorsal venous arch of the foot is a superficial vein that connects the small saphenous vein and the great saphenous vein. Anatomically, it is defined by where the dorsal veins of the first and fifth digit, respectively, meet the great saphenous vein and small saphenous vein.
The anterior tibial vein is a vein in the lower leg.
The superficial palmar arch is formed predominantly by the ulnar artery, with a contribution from the superficial palmar branch of the radial artery. However, in some individuals the contribution from the radial artery might be absent, and instead anastomoses with either the princeps pollicis artery, the radialis indicis artery, or the median artery, the former two of which are branches from the radial artery.
The frontal vein begins on the forehead in a venous plexus which communicates with the frontal branches of the superficial temporal vein. The veins converge to form a single trunk, which runs downward near the middle line of the forehead parallel with the vein of the opposite side. The two veins are joined, at the root of the nose, by a transverse branch, called the nasal arch, which receives some small veins from the dorsum of the nose. At the root of the nose the veins diverge, and, each at the medial angle of the orbit, joins the supraorbital vein, to form the angular vein. Occasionally the frontal veins join to form a single trunk, which bifurcates at the root of the nose into the two angular veins.
The dorsal venous network of the hand is a network of veins in the superficial fascia on the dorsum of hand formed by the dorsal metacarpal veins.
The external vertebral venous plexuses best marked in the cervical region, consist of anterior and posterior plexuses which anastomose freely with each other.
The internal vertebral venous plexuses lie within the vertebral canal in the epidural space, and receive tributaries from the bones and from the spinal cord.
In human anatomy, the dorsal veins of the penis comprise the superficial dorsal vein of the penis, the deep dorsal vein of the penis, the cavernosal veins of the penis, and the para-arterial veins of the penis.
The plantar metatarsal veins run backward in the metatarsal spaces, collect blood from digital veins and communicate, by means of perforating veins, with the veins on the dorsum of the foot, and unite to form the deep plantar venous arch which lies alongside the plantar arterial arch.
Just above the sternum the two anterior jugular veins communicate by a transverse trunk, the jugular venous arch, which receive tributaries from the inferior thyroid veins; each also communicates with the internal jugular.
The pudendal venous plexus lies behind the arcuate pubic ligament and the lower part of the pubic symphysis, and in front of the bladder and prostate. Its chief tributary is the deep dorsal vein of the penis, but it also receives branches from the front of the bladder and prostate. It communicates with the vesical venous plexus and with the internal pudendal vein and drains into the vesical and hypogastric veins.
The dorsal digital veins from the adjacent sides of the fingers unite to form three dorsal metacarpal veins, which end in a dorsal venous net-work opposite the middle of the metacarpus.
The volar digital veins on each finger are connected to the dorsal digital veins by oblique intercapitular veins. They drain into a venous plexus which is situated over the thenar and hypothenar eminences and across the front of the wrist.
The superficial palmar arch is accompanied by a pair of venae comitantes which constitute the superficial palmar venous arch. It receives the veins corresponding to the branches of the superficial arterial arch: the common palmar digital veins.
The deep palmar arch is accompanied by a pair of venae comitantes which constitute the deep palmar venous arch. It receives the veins corresponding to the branches of the arterial arch: the palmar metacarpal veins.
Anterior spinal veins are veins that receive blood from the anterior spinal cord.

Gray's Anatomy is an English language textbook of human anatomy originally written by Henry Gray and illustrated by Henry Vandyke Carter. Earlier editions were called Anatomy: Descriptive and Surgical, Anatomy of the Human Body and Gray's Anatomy: Descriptive and Applied, but the book's name is commonly shortened to, and later editions are titled, Gray's Anatomy. The book is widely regarded as an extremely influential work on the subject, and has continued to be revised and republished from its initial publication in 1858 to the present day. The latest edition of the book, the 41st, was published in September 2015.
