renal cortex

The renal cortex is the outer layer of the kidney, characterized by its granular texture and paler color compared to the inner medulla. This region houses the glomeruli and convoluted tubules, which are essential components of the nephrons. Nephrons are the functional units of the kidney, responsible for filtering blood and producing urine.123

Within the renal cortex, the renal corpuscle, also known as the malpighian body, is a key structure. It consists of a cluster of capillaries called the glomerulus, enclosed by Bowman's capsule. Blood pressure forces plasma from the glomerular capillaries into Bowman's capsule, forming capsular urine that then moves into the renal tubules for further processing. The initial portions of these tubules, including the proximal convoluted tubule, are located in the renal cortex.34
