What is the structural and functional unit of the human kidney?
A. Neuron
B. Nephron✓ Correct Answer
C. Alveolus
D. Haversian system
💡 Solution & Explanation
The nephron is established as the fundamental structural and functional filtration unit of the human kidney, responsible for removing waste products from blood and forming urine. Neurons serve as the functional units of the nervous system, whereas alveoli function within the respiratory gas exchange system. Each human kidney contains over a million nephrons performing complex filtration and reabsorption tasks. Human physiology questions in biology consistently feature structural unit identifications.
