The avian kidney is lobulated and usually consists of three lobes. [80] The lobes are divided into lobules, each of which has a cortex and a medulla. [ 67 ] [ 3 ] The medulla of the each lobule is shaped like a cone, and, unlike mammals, it is not subdivided into the inner and outer regions, while structurally it is similar to the outer medulla ...
A cortical lobule (or renal lobule) is a part of a renal lobe. It consists of the nephrons grouped around a single medullary ray , and draining into a single collecting duct . Its near identical parallel is the rectal lobe [ citation needed ] , which is present in the majority of mammals.
The renal circulation supplies the blood to the kidneys via the renal arteries, left and right, which branch directly from the abdominal aorta. Despite their relatively small size, the kidneys receive approximately 20% of the cardiac output .
The renal corpuscle is a blood-filtering part of the nephron and is located in the cortex. The renal tubule extends from the renal corpuscle to the medulla into the loop of Henle and then returns back to the cortex. Finally, the renal tubule flows with its distal end into its collecting duct, which is common to several nephrons.
Urology addresses diseases of kidney (and urinary tract) anatomy: these include cancer, renal cysts, kidney stones and ureteral stones, and urinary tract obstruction. [7] The word “renal” is an adjective meaning “relating to the kidneys”, and its roots are French or late Latin. Whereas according to some opinions, "renal" should be ...
The interlobar veins are veins of the renal circulation which drain the renal lobes. [citation needed] They collect blood from the arcuate veins. The interlobar veins unite to form a renal vein. [1] Each interlobar vein passes along the edge of the renal pyramids. [2]
The interlobar arteries are vessels of the renal circulation which supply the renal lobes. The interlobar arteries branch from the lobar arteries which branch from the segmental arteries, from the renal artery. They give rise to arcuate arteries. [1]
