Verified step by step guidance1
Understand that the kidney is composed of various structures, each with specific roles in processing and transporting urine.
Identify the main structures listed: Collecting duct, Ureter, Renal pelvis, and Nephron, and consider their functions within the kidney.
Recall that the functional unit of an organ is the smallest structure capable of performing all the organ's functions independently.
Recognize that the nephron is the microscopic structure responsible for filtering blood, reabsorbing needed substances, and forming urine, thus performing the kidney's essential functions.
Conclude that among the options, the nephron is the functional unit of the kidney because it carries out filtration and urine formation, while the other structures serve as conduits or collection areas.
