Verified step by step guidance

Step 1: Begin by understanding the anatomy of the human kidney, which is divided into three main regions: the renal cortex, the renal medulla, and the renal pelvis. These regions are responsible for different functions in the kidney's role of filtering blood and producing urine.

Step 2: The renal cortex is the outermost layer of the kidney, containing the glomeruli and parts of the nephron responsible for filtration and initial urine formation.

Step 3: The renal medulla is the middle region of the kidney, consisting of renal pyramids and tubules that concentrate urine and transport it to the renal pelvis.

Step 4: The renal pelvis is the innermost region of the kidney, acting as a funnel to collect urine from the renal medulla and direct it to the ureter.

Step 5: The renal capsule is not considered one of the three main regions of the kidney. It is a tough, fibrous outer layer that surrounds and protects the kidney but does not play a direct role in filtration or urine transport.
