1 Cortex â the outer region of the kidney; extensions of the cortical tissue, contains about one million blood filtering nephrons. 2  Nephron â these are the filtration units in the kidneys. 3  Medulla â inner region of the kidney contains 8-12 renal pyramids.
A third part of the nephron is a collecting duct that drains urine from the tubule. Each tubule has three interconnected parts: the proximal convoluted tubule, the loop of Henle, and the distal convoluted tubule. The kidneys consist of an outer part (cortex) and an inner part (medulla). All glomeruli are located in the cortex, while tubules are located in both the cortex and the medulla. The urine drains from the collecting ducts of many thousands of nephrons into a cuplike structure (calix). Each kidney has several calices, all of which drain into a single central chamber (renal pelvis).
