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. It contains the renal corpuscles and the renal tubules and it also contains blood vessels and cortical collecting ducts.
The renal cortex is basically the secondary layer of the kidneys in humans and most other mammals. It tends to be thicker than most of the organ’s inner tissues, and in many ways serves to protect the organ and keep it insulated.  the part of the kidney consisting of renal lobules in the outer zone beneath the capsule and the lobules of the renal columns that are extensions inward between the pyramids; contains the renal corpuscles, medullary rays, and proximal and distal convoluted tubules. Synonym(s): cortex renalis [TA]. cerebral cortex (cortex cerebra´lis) the convoluted layer of gray matter covering each cerebral hemisphere. See also brain. renal cortex the granular outer layer of the kidney, composed mainly of glomeruli and convoluted tubules, extending in columns between the pyramids that constitute the renal medulla. The renal cortex is the kidney’s external section and comprise of medulla pyramids that filters around 43 gallons of water every day via nephrons which are small structures present in millions inside these pyramids. Every group of 10000 nephrons constitute small vessel clusters termed as glomerulus capillaries. Each kidney is broadly divided into an external part called as renal cortex and an internal part termed as medulla. The main function of a renal cortex is to filter blood and remove unwanted substances out of the body. renal cortex, the highly vascularized granular outer layer of the kidney, containing approximately 1.25 million glomeruli and convoluted tubules, which filter body wastes from the blood, reclaim useful materials, and dispose of the remainder as urine. cerebral cortex (cortex cerebra´lis) the convoluted layer of gray matter covering each cerebral hemisphere. See also brain. renal cortex the granular outer layer of the kidney, composed mainly of glomeruli and convoluted tubules, extending in columns between the pyramids that constitute the renal medulla. The renal medulla 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 interlobar arteries. The renal medulla is hypertonic to the filtrate in the nephron and aids in the reabsorption of water. Blood is filtered in the glomerulus by solute size. Ions such as sodium, chloride, potassium, and calcium are easily filtered, as is glucose. 1 Cortex – the outer region of the kidney; extensions of the cortical tissue, contains about one million blood filtering nephrons. 2  Nephron – these are the filtration units in the kidneys. 3  Medulla – inner region of the kidney contains 8-12 renal pyramids. 4  The pyramids empty into the calyx.  For other uses, see Cortex (disambiguation) . The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla. In the adult, it forms a continuous smooth outer zone with a number of projections (cortical columns) that extend down between the pyramids. 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. Erythropoietin is produced in the renal cortex.
