Question:
The functional unit of kidney is:
The functional unit of kidney is:
Show Hint
Don't confuse \textbf{Nephron} (Kidney/Excretion) with \textbf{Neuron} (Brain/Nervous System). They sound similar but belong to completely different systems!
Updated On: Mar 29, 2026
- Neuron
- Nephron
- Alveoli
- Glomerulus

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
The kidney filters waste from the blood. This filtration happens across millions of tiny microscopic structures that perform the actual work of excretion.
Step 2: Detailed Explanation:
The Nephron is the structural and functional unit of the kidney. Each kidney contains about one million nephrons which filter blood, reabsorb useful substances, and form urine. (A neuron is for the nervous system; alveoli are for the lungs).
Step 3: Final Answer:
The correct option is (b).
