Answer
Exam answer
The kidney is composed of a number of NEPHRONS.
Explanation
Two words that look alike and belong to entirely different systems: NEPHRON — the structural and functional unit of the KIDNEY, about a million in each. It filters blood and forms urine. NEURON — the structural and functional unit of the NERVOUS SYSTEM. It conducts impulses.
Both are described as "the structural and functional unit" of their system, which is the only thing they have in common — and precisely why examiners pair them.
Keep the spelling apart: nePHron for the kidney, neUron for the nerve.
