In the human kidney, the renal cortex is the granular outer layer that houses several critical components of the nephron, which is the functional unit responsible for urine production.12
The structures found within the renal cortex include:
- Renal Corpuscles: Each consists of a glomerulus (a cluster of capillaries) enclosed within Bowmanâs capsule.31
- Convoluted Tubules: This includes both the proximal convoluted tubule and the distal convoluted tubule.12
- Blood Vessels: The cortex contains a rich network of vessels, including interlobular arteries, afferent and efferent arterioles, and capillary networks that supply the nephrons.45
- Juxtaglomerular Apparatus: A specialized structure located near the point where the afferent arteriole enters the glomerulus, involved in the secretion of the enzyme renin.4
While the nephron tubules extend into the medulla as the loop of Henle, the initial portions and the corpuscles remain situated in the cortical region.12
