Step 2: Recognize that the nephron is the microscopic functional unit within the kidney responsible for filtering blood and forming urine.
Step 3: Differentiate between the terms: the ureter is a tube that carries urine from the kidney to the bladder; the renal pelvis is a funnel-shaped structure that collects urine from the nephrons; the renal cortex is the outer layer of the kidney where many nephrons are located.

Step 5: Conclude that among the options given, the nephron is the correct answer as it is the functional unit of the kidney.
