| segmental arteries of kidney | The branches of the renal artery that supply the anatomical segments of kidney. Usually five in number, they are end arteries and give off interlobar, arcuate and interlobular arteries in sequence. The latter send afferent arterioles to the glomeruli as well as branches to the kidney capsule. The segmental arteries of the kidney are identified as: anterior inferior (arteriae segmenti anterioris inferioris renis ); anterior superior (arteriae segmenti anterioris superioris renis ); inferior (arteriae segmenti inferioris renis ); posterior (arteriae segmenti posterioris renis ); and superior (arteriae segmenti superioris renis ). Synonym: arteriae renis, arteries of kidney. (05 Mar 2000) |
| pulmonary arteries | <anatomy> The pulmonary arteries deliver deoxygenated blood from the right ventricle to the lungs. They are the only arteries in the human body that carry deoxygenated blood. (27 Sep 1997) |
| short gastric arteries | Four or five small arteries given off from the splenic, passing via the gastrosplenic ligament to the fundus of the stomach along the greater curvature, and anastomosing with the other arteries in that region. Synonym: arteriae gastricae breves, vasa brevia. (05 Mar 2000) |
| sigmoid arteries | Origin, inferior mesenteric; distribution, descending colon and sigmoid flexure; anastomoses, left colic, superior rectal. Synonym: arteriae sigmoideae. (05 Mar 2000) |
