The Thoracic Aorta The Thoracic Aorta (portion of descending aorta) descends through the thorax. Visceral branches: > pericardial - posterior pericardium > bronchial - 2 left, 1 right supplying blood to the lungs and bronchial pleurae > esophageal - esophagus > mediastinal - posterior mediastinum Parietal branches: > posterior intercostals - 9-10 pairs - anastomose around the front with anterior intercostals > superior phrenics - posterior diaphragm The Abdominal Aorta The Abdominal Aorta pierces diaphragm and enters abdominal cavity and is now abdominal aorta over the vertebral column. It gives off the following branches: > inferior phrenic - to supply the inferior diaphragm > celiac trunk gives off 3 branches: 1. common hepatic artery - gives off a complex group of arteries to the stomach: • right gastric artery which meets up (anastomoses) with left gastric artery to supply the lesser curvature of the stomach. • right gastroepiploic artery that meets up (anastomoses) with left gastroepiploic artery (branch of splenic artery) to supply the greater curvature of the stomach. 2. splenic artery (to spleen), 3. left gastric artery (to stomach) > superior mesenteric - to supply the midgut (duodenum to mid-transverse colon) > suprarenals - to supply the adrenal gland > renals - to supply the kidneys > gonadals - to supply the testes and ovaries > inferior mesenteric - to supply the hindgut (mid-transverse colon to rectum) > lumbar arteries - several pairs off the posterior side of the descending aorta > median sacral artery - off the posterior side of the descending aorta > common iliac arteries - where descending aorta splits at L4 to supply blood to the lower limbs, pelvic organs and lower abdominal wall.
