Aorta

aorticaortic archaortic root
As part of the aorta, it is a direct continuation of the descending aorta (of the thorax).
The aorta then continues downward as the abdominal aorta (or abdominal portion of the aorta) from the diaphragm to the aortic bifurcation.

Superior mesenteric artery

superiorSuperior mesentericcranial mesenteric artery
In human anatomy, the superior mesenteric artery (SMA) arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.

Middle suprarenal arteries

middle suprarenal arterymiddle suprarenal
The middle suprarenal arteries (middle capsular arteries; suprarenal arteries) are two small vessels which arise, one from either side of the abdominal aorta, opposite the superior mesenteric artery.

Testicular artery

internal spermatic arteryinternal spermatic vesselsspermatic vessels
The testicular artery (the male gonadal artery, also called the internal spermatic arteries in older texts) is a branch of the abdominal aorta that supplies blood to the testis.

Descending aorta

descending thoracic aortadorsal aortaproximal descending aorta
As part of the aorta, it is a direct continuation of the descending aorta (of the thorax).
The descending aorta anatomically consists of two portions or segments, the thoracic and the abdominal aorta, in correspondence with the two great cavities of the trunk in which it is situated.

Ovarian artery

It arises from the abdominal aorta below the renal artery.

Inferior mesenteric artery

inferior mesenteric arteriesinferior mesentericinferior
The collateral circulation would be carried on by the anastomoses between the internal thoracic artery and the inferior epigastric artery; by the free communication between the superior and inferior mesenterics, if the ligature were placed between these vessels; or by the anastomosis between the inferior mesenteric artery and the internal pudendal artery, when (as is more common) the point of ligature is below the origin of the inferior mesenteric artery; and possibly by the anastomoses of the lumbar arteries with the branches of the internal iliac artery.
In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal.

Renal artery

The renal arteries normally arise off the left interior side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood.

Inferior vena cava

inferiorIVCposterior vena cava
Note that the bifurcation (union) of the inferior vena cava is at L5 and therefore below that of the bifurcation of the aorta.

Duodenum

duodenaldodecadactylumduodenal cap
It is covered, anteriorly, by the lesser omentum and stomach, behind which are the branches of the celiac artery and the celiac plexus; below these, by the lienal vein (splenic vein), the pancreas, the left renal vein, the inferior part of the duodenum, the mesentery, and aortic plexus.
It begins at the inferior duodenal flexure and passes transversely to the left, passing in front of the inferior vena cava, abdominal aorta and the vertebral column.

Human leg

In the pelvis area, at the level of the last lumbar vertebra, the abdominal aorta, a continuation the descending aorta, splits into a pair of common iliac arteries.

Nutcracker syndrome

left renal vein entrapmentNutcrackerNutcracker effect
The nutcracker syndrome (NCS) results most commonly from the compression of the left renal vein (LRV) between the abdominal aorta (AA) and superior mesenteric artery (SMA), although other variants exist.

Aortocaval compression syndrome

aortocaval compressionSupine hypotensive syndrome
Aortocaval compression syndrome is compression of the abdominal aorta and inferior vena cava by the gravid uterus when a pregnant woman lies on her back, i.e. in the supine position.

Lumbar arteries

lumbar arterylumbarArteria lumbalis
The collateral circulation would be carried on by the anastomoses between the internal thoracic artery and the inferior epigastric artery; by the free communication between the superior and inferior mesenterics, if the ligature were placed between these vessels; or by the anastomosis between the inferior mesenteric artery and the internal pudendal artery, when (as is more common) the point of ligature is below the origin of the inferior mesenteric artery; and possibly by the anastomoses of the lumbar arteries with the branches of the internal iliac artery.

Celiac artery

celiac trunkceliacceliac axis
The coeliac artery, also known as the coeliac trunk, or truncus coeliacus, is the first major branch of the abdominal aorta.

Descending thoracic aorta

thoracic aortathoracicthoracic part
The descending thoracic aorta begins at the lower border of the fourth thoracic vertebra where it is continuous with the aortic arch, and ends in front of the lower border of the twelfth thoracic vertebra, at the aortic hiatus in the diaphragm where it becomes the abdominal aorta.

Circulatory system

It branches from the abdominal aorta and returns blood to the ascending vena cava.

Abdominal cavity

The abdominal aorta is the largest artery in the abdominal cavity.
