Question

The basic functional and structural unit of human kidney is:

• A. Nephron
• B. Neuron
• C. Nephridia
• D. Malpighian tubules

Answer 1

The correct option is A Nephron

The nephron is the basic structural and functional unit of the kidney. It is a microscopic structure that regulates water and soluble substances in the blood by filtering the blood, reabsorbing what is needed, and excreting the rest as urine. Hence, helps in urine formation.

A neuron is the fundamental unit of the nervous system.

Nephridia are organs of excretion in some invertebrates.

The malpighian tubule is the excretory organ of insects,

So, the correct answer is option A.
