Abdominal Aorta
Azhar nazir kiani
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

Branches of Abdominal Aorta:
Celiac Artery Superior Mesenteric Artery Inferior Mesenteric Artery Common iliac Artery Inferior phrenic arteries Middle suprarenal arteries Renal arteries Gonadal arteries Median sacral artery Lumbar arteries

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.

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.

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.

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. Azhar nazir kiani
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.

Middle suprarenal arteries
These are the two small vessels. The adrenal glands are supplied by middle
suprarenal arteries
Azhar nazir kiani
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.

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