5. Abdominal Aorta:
 The abdominal aorta is the largest artery in the abdominal
cavity.
 It is part of the aorta.
 The abdominal aorta is a continuation of the thoracic aorta
beginning at the level of the T12 vertebrae.
 It is approximately 13cm long and ends at the level of the L4
vertebra.
 At L4, the aorta terminates by bifurcating into the right and
left common iliac arteries that supply the lower body

8. Celiac Artery:
 Celiac artery also known as the celiac trunk.
 It is the first major branch of the abdominal aorta.
 It is 1.25 cm in length.
 There are three main divisions of the celiac artery, and each in turn has its own
named branches.
 Left gastric artery
 Common hepatic artery
 Splenic artery
 Left gastric Artery supplies blood to stomach and esophagus.
 Common hepatic artery supplies blood to liver, pylorus of the stomach,
duodenum and pancreas.
 Splenic artery supplies blood to spleen.

9. Superior Mesenteric Artery:
 The superior mesenteric artery (SMA) is a major artery of the abdomen.
 It is usually 1 cm lower than the celiac trunk.
 It has 5 branches.
 Inferior Pancreaticoduodenal Artery
 intestinal arteries
 ileocolic artery
 right colic artery
 middle colic artery
 Inferior pancreticodudenal Artery supplies blood to head of the pancreas and to
the ascending and inferior parts of the duodenum.
 Intestinal arteries branches to ileum, branches to jejunum.
 ileocolic artery supplies last part of ileum.
 Right colic artery to ascending colon.
 Middle colic artery also supplies blood to colon.

10. Inferior Mesenteric Artery:
 It supplies arterial blood to the organs of the hindgut.
 It has three branches:
 left colic artery
 sigmoid branches
 superior rectal artery
 Left colic artery supplies blood to descending colon.
 Sigmoid branches supplies blood to sigmoid colon.
 Superior rectal artery supplies Rectus.

11. Common iliac Artery:
The abdominal aorta divides to form the
"common iliac arteries" in the lower
abdomen.
These vessels supply blood to the pelvic
organs, gluteal region, and legs.
Each common iliac artery descends a
short distance and divides into
an internal and an external branch.

12. Inferior phrenic arteries:
The inferior phrenic arteries are two small
vessels.
These supply blood to the diaphragm.
They may arise separately from the front of
the aorta, above the celiac artery.

13. Middle suprarenal arteries
These are the two small vessels.
The adrenal glands are supplied by middle
suprarenal arteries

14. Renal arteries:
The renal arteries normally arise off the side
of the abdominal aorta, below the superior
mesenteric artery.
Renal arteries supply the kidneys with blood.

15. Gonadal arteries:
It is also called testicular artery.
It is the branch abdominal aorta
that supplies blood to the testes.
It is a paired artery, and supply each testis
separately.

16. Median sacral artery:
The median sacral artery ( middle sacral
artery) is a small vessel.
Its supplies blood to coccyx, lumbar
vertebrae, sacrum.

17. Lumbar arteries:
The lumbar arteries are arteries located
in the lower back or lumbar region.
They are usually four in numbers.
These supplies blood to Quadratus
lumborum.
