Kidney left and right, which branch directly from the abdominal aorta. Despite their relatively small size, the kidneys receive approximately 20% of the cardiac output. Each renal artery branches into segmental arteries, dividing further into interlobar arteries, which penetrate the renal capsule and extend through the renal columns between the renal pyramids. The interlobar arteries then supply blood to the arcuate arteries that run through the boundary of the cortex and the medulla. Each arcuate artery supplies several interlobular arteries that feed into the afferent arterioles that supply the glomeruli. After filtration occurs, the blood moves through a small network of
Gastroduodenal artery Gastroduodenal artery In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen. It supplies blood directly to the pylorus (distal part of the stomach) and proximal part of the duodenum, and indirectly to the pancreatic head (via the anterior and posterior superior pancreaticoduodenal arteries). The gastroduodenal artery most commonly arises from the common hepatic artery of the celiac trunk, but there are numerous variations of the origin. It first gives rise to the supraduodenal artery, followed by the posterior superior pancreaticoduodenal artery. It terminates in a bifurcation when it splits into the right gastroepiploic artery and the
