Functional unit of Kidney is

Options

A. neuron
B. axon
C. glomerulus
D. nephron

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for the functional unit of the kidney. We need to identify which of the given options (neuron, axon, glomerulus, nephron) is correct.

2. **Analyzing the Options:**
- **Neuron:** This is a unit of the nervous system, not related to kidney function.
- **Axon:** This is part of a neuron, also related to the nervous system.
- **Glomerulus:** This is a network of capillaries involved in the filtration of blood, but it is not the entire functional unit of the kidney.
- **Nephron:** This is the correct answer. The nephron is the functional unit of the kidney responsible for filtering blood and forming urine.

3. **Defining the Nephron:**
The nephron consists of two main parts:
- **Malpighian Capsule (Bowman's Capsule):** This is where the filtration of blood occurs.
- **Urinary Tubule:** This is where the filtered fluid is processed to form urine.

4. **Conclusion:**
The functional unit of the kidney is the nephron, which plays a crucial role in the excretion of waste products and regulation of water and electrolyte balance in the body.

**Final Answer:** The functional unit of the kidney is the **nephron**.
