The superior adrenal (suprarenal) arteries are a group of arteries that together form one of the three adrenal arteries that supply the adrenal gland. There are usually numerous small arteries arising from the inferior phrenic artery.

Arteries - Renal

carry blood from the heart to the kidneys. They branch directly from the aorta (the main artery coming off the heart) on either side and extend to each kidney. These arteries take a very large volume of blood to the kidneys to be filtered.

Arteries - Gonadal (Testicular or Ovarian)

paired primary vascular supply to the ovaries in the female and the testes in the male. As the anatomy of the gonadal arteries differs substantially between the sexes, they are covered separately: ovarian arteries. testicular arteries

Veins - Internal thoracic

arises from the superior epigastric vein. It drains the chest wall and breasts.

Veins - Azygous

a vein running up the right 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.

Veins - Brachicephalic

a paired vein of the superior mediastinum that drains the venous blood from the head and neck, upper limbs and the upper part of the thorax. It is formed by the confluence of the internal jugular and subclavian veins on each side, just posterior to the sternoclavicular joint.

a paired large vein, one on either side of the body, that is responsible for draining blood from the upper extremities, allowing this blood to return to the heart.

Veins - Axillary

a deep vein of the upper limb that is formed by the union of the brachial and basilic veins. It starts at the lower border of the teres major muscle and ascends medially through the axilla towards the 1st rib, where it is continued by the subclavian vein.

Veins - Brachial

accompanies the brachial artery in the region of the arm. It is formed by the unification of the ulnar and radial veins at the elbow. The basilic vein joins the brachial vein and becomes the axillary vein at the inferior border of the teres major muscle. At it its terminal part the axillary vein is joined by the cephalic vein (this vein runs in the deltopectoral groove). At the lateral margin of the first rib axillary vein continues as the subclavian vein.

Veins - Radial

paired veins that accompany the radial artery through the back of the hand and the lateral aspect of the forearm. They join the ulnar veins to form the brachial veins. They follow the same course as the radial artery.

Veins - Ulnar

Veins - Basilic

a large superficial vein of the upper limb that helps drain parts of the hand and forearm.

Veins - Cephalic

a superficial vein of the upper limb and it's one of the two main veins of the arm. Its name derives from 'cephalic' meaning head, as the vein runs up to the shoulder. The superficial venous network is the source of blood for most blood tests, and is the easiest place to access venous blood.

Veins - Median cubital

a prominent superficial upper limb vessel. Its location is in the cubital fossa, on the anterior/flexor aspect of the elbow joint. This region of the upper limb is sometimes referred to as the antecubital area.

Veins - Internal jugular

a paired vessel found within the carotid sheath on either side of the neck. It extends from the base of the skull to the sternal end of the clavicle.

Veins - Lingual

a blood vessel that arises from the union of the dorsal lingual vein and the deep lingual vein. The lingual vein passes adjacent to the hyoglossus muscle and drains into the internal jugular vein.

Veins - Facial

a paired vessel and the main vein of the face. The facial veins stem from the angular veins on each side of the root of the nose.

Veins - Vertebral

a paired vessel found in the transverse foramina of the cervical vertebrae on either side of the neck. It arises at the level of the sixth cervical vertebra from a venous plexus that surrounds the vertebral artery and travels as far as the brachiocephalic veins.

Veins - Dural sinuses

are venous channels located intracranially between the two layers of the dura mater (endosteal layer and meningeal layer). They can be conceptualised as trapped epidural veins. Unlike other veins in the body, they run alone, not parallel to arteries.

Veins - Inferior vena cava

a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart.

Veins - Hepatic

the veins that drain de-oxygenated blood from the liver into the inferior vena cava. There are usually three upper hepatic veins draining from the left, middle, and right parts of the liver. These are larger than the group of lower hepatic veins that can number from six to twenty.

Veins - Suprarenal

The Suprarenal veins are two in number: the right ends in the inferior vena cava. the left ends in the left renal or left inferior phrenic vein. They receive blood from the adrenal glands and will sometimes form anastomoses with the inferior phrenic veins.

Veins - Renal

veins that drain the kidney. They connect the kidney to the inferior vena cava. They carry the blood filtered by the kidney.

Veins - Gonadal

paired structures that drain the gonads in males and females. In males it is called the testicular vein (or internal spermatic vein) and in females it is called the ovarian vein. The gonadal veins ascend with the gonadal arteries in the abdomen along the psoas muscle anterior to the ureters.

Veins - Lumbar

four pairs of blood vessels that drain the lumbar segments of the spinal cord, posterolateral abdominal wall and lumbar structures of the back. They usually empty into the inferior vena cava, but they can also drain into the ascending lumbar, azygos, renal or other lumbar veins.

Veins - Common iliac

(created by the union of the internal and external iliac veins) forms in the abdomen, at the level of the fifth lumbar vertebrae. It divides into two branches. The internal iliac vein drains blood from the visceral organs in the pelvic region. The external iliac connects to the femoral veins.

Veins - Internal iliac

begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to form the common iliac vein.

Veins - External iliac

large veins that connect the femoral veins to the common iliac veins. Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins (to form the common iliac veins).

Veins - Femoral

a direct continuation of the popliteal vein just proximal to the knee. The vein ascends to the inguinal region, where it passes posterior to the inguinal ligament as the external iliac vein to enter the abdomen. The main function of the femoral vein is to drain the lower limb.

Veins - Great saphenous

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.

Veins - Deep femoral

(deep vein of the thigh) empties into the femoral vein posteriorly, about 8 cm distal to the inguinal ligament. It is formed by perforating veins that drain the surrounding muscles. Proximal to the entry point of the deep femoral vein, the femoral vein is often referred to as the common femoral vein.

Veins - Popliteal

a deep vein of the leg. It drains blood away from the leg into the femoral vein, which drains blood to the inferior vena cava to return to the right atrium of the heart

Veins - Anterior tibial

paired veins located in the anterior compartment of the leg. These veins accompany the anterior tibial artery, coursing over the anterior interosseous membrane of the leg.

Veins - Posterior tibial

the paired vessels found in the posterior compartment of the leg. They are the venae comitantes of the posterior tibial artery and are closely related to it during their entire course.

Veins - Hepatic portal vein

a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver. This blood contains nutrients and toxins extracted from digested contents.
