CThe renal calyces
DThe renal columns
Answer & Solution
Correct answer: A. The kidney nephrons
1. The kidney's cleansing work happens in repeating microscopic units.
2. Nephrons are the functional units of the kidney; they cleanse the blood and balance the circulation.
3. Pyramids, columns, and calyces are gross anatomy landmarks, not the working units.
