120+121. Abdominal aorta - paired and unpaired branches.
Covers the course of the abdominal aorta from the aortic hiatus to its bifurcation at the fourth lumbar vertebra, then sets out its branches. Visceral branches are grouped into single branches (celiac trunk with its gastric, splenic, hepatic and pancreatic arteries, plus superior and inferior mesenteric) and paired branches (adrenal, renal and gonadal), while parietal branches are the inferior phrenic and lumbar arteries. Each branch is paired with the organ or region it supplies.
