B
Ureter
C
Renal pyramid
D
Renal capsule
Verified step by step guidance
1
Understand that the kidney is composed of several anatomical structures, each with specific functions related to urine formation and filtration.
Identify the term 'basic functional unit' as the smallest structure capable of performing the essential functions of the kidney, such as filtering blood and forming urine.
Recall that the nephron is the microscopic structure within the kidney responsible for filtering blood, reabsorbing needed substances, and secreting waste products into urine.
Differentiate the nephron from other options: the ureter is a duct that transports urine from the kidney to the bladder, the renal pyramid is a larger structural region within the kidney, and the renal capsule is the outer protective layer of the kidney.
Conclude that the nephron is the correct answer because it is the fundamental unit that carries out the kidney's primary functions.
