The arterial supply of the kidneys is variable and there may be one or more renal arteries supplying each kidney. [1] It is located above the renal vein. Supernumerary renal arteries (two or more arteries to a single kidney) are the most common renovascular anomaly, occurrence ranging from 25% to 40% of kidneys. [8] Aberrant renal arteries may ...
[2] [3] They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres (4 + 1 ⁄ 2 inches) in length. [4] [5] They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder.
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.
The arcuate arteries of the kidney, also known as arciform arteries, [1] are vessels of the renal circulation. They are located at the border of the renal cortex and renal medulla. They are named after the fact that they are shaped in arcs due to the nature of the shape of the renal medulla. Arcuate arteries arise from renal interlobar arteries ...
From anterior to posterior, the renal vein exits, the renal artery enters, and the renal pelvis exits the kidney. On the left hand side the hilum is located at the L1 vertebral level and the right kidney at level L1-2. The lower border of the kidneys is usually alongside L3.
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 .
In the mammalian kidney, they follow two markedly different courses, depending on the location of the glomeruli from which they arise. In the mammalian kidney, about 15% of glomeruli lie close to the boundary between the renal cortex and renal medulla and are known as juxtamedullary glomeruli. The rest are simply undifferentiated cortical ...
The renal medulla (Latin: medulla renis 'marrow of the kidney') is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids. Blood enters into the kidney via the renal artery, which then splits up to form the segmental arteries which then branch to form interlobar arteries.
