The abdominal aorta is a major blood vessel that supplies oxygenated blood to the abdominal region and lower limbs. It is the continuation of the aorta, the main artery that carries oxygenated blood from the heart to the rest of the body. The abdominal aorta is divided into paired branches, which include the left and right common iliac arteries, the left and right external iliac arteries, and the left and right internal iliac arteries.

The common iliac arteries are the largest branches of the abdominal aorta, and they provide blood supply to the pelvis and lower limbs. They branch off from the aorta at the level of the fourth lumbar vertebra and divide into the external and internal iliac arteries. The external iliac arteries supply blood to the muscles and skin of the lower limbs, while the internal iliac arteries supply blood to the pelvis and reproductive organs.

The internal iliac arteries are smaller branches that branch off from the common iliac arteries. They supply blood to the pelvic region and reproductive organs, including the bladder, uterus, and prostate gland. The internal iliac arteries also give rise to smaller branches that supply blood to the gluteal region and the lower limbs.

The paired branches of the abdominal aorta play a crucial role in the circulation of blood in the body. They ensure that the abdominal region and lower limbs receive an adequate supply of oxygenated blood, which is essential for maintaining good health. Dysfunction of these arteries can lead to various health problems, including aneurysms, occlusions, and stenosis, which can be life-threatening if left untreated. Therefore, it is important to maintain the health of these arteries through a healthy lifestyle and regular medical check-ups.

The inferior suprarenal arteries supply the gonads and other organs found near the kidneys. Gastroepiploica dextra goes to the left along the large curvature of the stomach, anastomoses with the same left artery, giving numerous branches to the stomach and a large epiploon - glandular branches rr. Several smaller branches, including the celiac artery and the gonadal artery, have developed as a result. It is most commonly developed in the abdominal aorta, followed by the ascending aorta and aortic arch. Trauma to the abdominal aorta can result from either blunt trauma e. The arteries begin at T12 and end at L4, where they connect to the common iliac arteries.

Note: During the embryological period, the gastrointestinal tract organs are derived from the primitive gut tube, which is divided into three portions: foregut, midgut and hindgut. It happens at the level of the inferior border of the twelfth thoracic vertebra T12. In the event of a trifurcation, the left gastric artery is the primary vessel, whereas the liver and splenic arteries are the primary arteries. It supplies the spleen, pancreas, and stomach with oxygen. Remembering the branches of abdominal aorta is a bit tricky, but can be done by memorizing mnemonics and tricks.

This terminal branch of the carotid artery is the primary primitive brain branch of fishes, amphibians, reptiles, and birds. There are about 90% of these occurrences that occur alone. Also, the aortic arch is crossed by the following structures - left phrenic nerve , left inferior cardiac branch of the vagus nerve CN X , left superior cervical cardiac branch of the sympathetic trunk , left superior intercostal vein and left vagus nerve. It usually originates at the level of the inferior border of the body of the twelfth thoracic vertebra T12. Human ACA formation is more likely the variant of extensive fusion rather than the incidental appearance of primitive forms.

One of them anastomoses with the branch of the sigmoid artery and supplies blood to the lower sections of the sigmoid colon. The celiac artery is the aortic branch, whereas the superior mesenteric artery, inferior mesenteric artery, renal artery, and iliac artery are aortic branch arteries. The kidneys on either side of the renal arteries can be supplied via either of the arteries around L1 or L2. An incomplete tree is one with the coeliac, superior mesenteric, inferior mesenteric, and median sacral arteries.

Because the abdominal aorta is smaller than other aortic segments, it is more prone to aortic dissection. Assuming you would like tips on how to remember the paired branches off the aorta: One way to remember the paired branches off the aorta is to think of them in terms of the anatomy. When you are suffering from coronary artery disease, you should make sure to have regular artery check-ups. When the diaphragmatic hiatus is reached, the abdominal aortic system begins. When the renal arteries reach the kidneys, they are approximately 2. The common hepatic artery, the splenic artery, and the left gastric artery. In the abdominal cavity the aorta gives off a number of branches, which form an extensive network supplying blood to the stomach, liver, pancreas, spleen, small and large intestines, kidneys, reproductive glands, and other organs.

The small intestine, as you might expect, is a long twisted tube that begins at the stomach and ends at the rectum. Also, the abdominal aorta is related to the ascending part of the duodenum and left sympathetic trunk. The thoracic aorta originates at the level of the aortic valve of the heart. The midgut develops into the rest of the duodenum, small intestine, and large intestine up to the proximal two-thirds of the transverse colon. Image by — pinimg There are three unpaired branches of the abdominal aorta: the celiac trunk, the superior mesenteric artery, and the inferior mesenteric artery. At first, it lies anterior to the tracheal bifurcation, but as it forms an arch, it is found on the left side of the trachea and esophagus.

Also, they give branches to the deep back muscles and spinal cord. Colica media departs from the superior mesenteric artery above the origin of the right colon, is upward to the transverse colon, and supplies the upper and upper divisions of the ascending colon. Because the IVC is in the way, the right renal artery has to pass behind it to get to the right kidney. The stomach is a small spongy organ located in the upper left corner of the stomach. The renal artery and the lumbar artery are the sources of the posterior branch. The superior mesenteric artery is the second major branch of the abdominal aorta. The ascending aorta originates from the aortic orifice at the base of the left ventricle , approximately at the inferior border of the third left costal cartilage behind the left half of the sternal body.

An aortic aneurysm is a localized enlargement of the aortic wall in the aortic system. Internal organs included in the abdomen are the internal pudendal, uterine, uterine, and rectal cells. The inferior mesenteric artery supplies blood to the rectum and the large intestine. The right common carotid artery supplies blood to the right side of the neck and head, including the right side of the brain. The first and often largest visceral branch of the abdominal aorta is the celiac trunk. Arteries Of The Abdominal Aorta The inferior mesenteric artery, which forms about 4 cm above the bifurcation of the abdominal aorta, is located at the level of L3 vertebra and lacks bifurcation. It enters the abdomen through the aortic opening of the diaphragm, which is located beneath the median arcuate ligament between the crura of the diaphragm at T12.

What is the first branch of the abdominal aorta? The abdominal aorta descends within the retroperitoneal space anterior to the bodies of the lumbar vertebrae. Lower abdominal organs, such as the intestines, bladder, and rectum, are transported by this artery. The ascending aorta is one of the great vessels of the heart and is located within the pericardium. The aortic arch ends on the left side at the level of the fourth thoracic vertebrae T4. Source: pinimg The adrenal, renal, gonadal, inferior phrenic, and lumbar arteries are the Paired branches of the nephrovascular system.
