It contains the renal corpuscles and the renal tubules except for parts of the loop of Henle which descend into the renal medulla. It also contains blood vessels and cortical collecting ducts. The renal cortex is the part of the kidney where ultrafiltration occurs. [2] Erythropoietin is produced in the renal cortex. [3]
The renal columns, Bertin columns, or columns of Bertin, a.k.a. columns of Bertini are extensions of the renal cortex in between the renal pyramids. They allow the cortex to be better anchored. (Cortical extensions into the medullary space.) Each column consists of lines of blood vessels and urinary tubes and a fibrous material. A hypertrophied ...
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 simplest type of kidney in mammals is the unipapillary kidney, consisting of a cortex, medulla, and renal pelvis. [163] But the unipapillary kidney is limited by the number of nephrons at which it functions optimally. [20] It is assumed that unipapillary kidney was the original kidney structure in mammals, from which multilobar kidneys ...
The functional substance, or parenchyma, of the human kidney is divided into two major structures: the outer renal cortex and the inner renal medulla. Grossly, these structures take the shape of eight to 18 cone-shaped renal lobes, each containing renal cortex surrounding a portion of medulla called a renal pyramid. [18]
In anatomy and zoology, the cortex (pl.: cortices) is the outermost, otherwise known as superficial, ... The renal cortex, here denoted by the number 2.
Diagram of the circulation related to a single glomerulus, associated tubule, and collecting system The renal corpuscle in the cortex (outer layer) of the kidney. At the top, the renal corpuscle containing the glomerulus. The filtered blood exits into the renal tubule as filtrate, at right. At left, blood flows from the afferent arteriole (red ...
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 ...
