2024年11月7日 · The abdominal aorta starts just below the diaphragm and runs down the back of the abdomen. It supplies oxygenated blood to vital organs, including the kidneys, stomach, intestines, and liver, through three main branches: the celiac artery, superior mesenteric artery, and renal arteries.

2025年2月4日 · The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta. It terminates at the level of L4 by bifurcating into the left and right common iliac arteries.

The abdominal aorta supplies blood to much of the abdominal cavity. It begins at T12 and ends at L4 with its bifurcation into the common iliac arteries [1] and usually has the following branches:

2023年10月30日 · Similarly to the branches of the thoracic aorta, the branches of the abdominal aorta can be grouped as visceral and parietal. However, a more commonly used classification is based on where the branches arise off of the aorta and …

2025年2月10日 · The abdominal aorta (plural: aortas or aortae 4) is the main blood vessel in the abdominal cavity that transmits oxygenated blood from the thoracic cavity to the organs within the abdomen and to the lower limbs.

2016年7月1日 · The abdominal aorta reduces the diameter rapidly because the branches are large and numerous (Figs. 18.1, 18.2). The aorta is in contact, anteriorly with the celiac plexus and the lesser sac or omental bursa, and the pancreatic body with the …

2023年7月25日 · The aorta is the main artery of the human body. It arises from the left ventricle of the heart and travels superiorly to form the ascending aorta. It then loops inferiorly to form the arch of the aorta and through the thorax to form the thoracic aorta. After crossing the diaphragm into the abdomen, the aptly-named abdominal aorta eventually bifurcates into the common …

The three paired branches arise from the abdominal aorta between the superior mesenteric artery and inferior mesenteric artery. They are the middle suprarenal arteries, the renal arteries, and the gonadal (ovarian or testicular) arteries.

2023年7月25日 · The lowest branching arteries of the thoracic aorta are the subcostal arteries which will later give off a posterior branch. The abdominal aorta gives rise to five major branches: the celiac trunk, superior mesenteric artery, left and right renal arteries, and …
