Options

A. Nephron
B. Neuron
C. Nephridia
D. Kidney

Answer

**Step-by-Step Solution:**

1. **Identify the Excretory System in Humans**: The human excretory system is primarily responsible for the removal of waste products from the body. The main organ involved in this process is the kidney.

2. **Understand the Structure of the Kidney**: The kidneys are bean-shaped organs that are paired (two kidneys in the human body). They play a crucial role in filtering blood and producing urine.

3. **Recognize the Excretory Unit**: Within each kidney, there are millions of microscopic structures known as nephrons. These nephrons are the basic structural and functional units of the kidney.

4. **Components of Nephrons**: Each nephron consists of two main parts:
- **Glomerulus**: A network of capillaries where the filtration of blood occurs.
- **Renal Tubule**: The part of the nephron where the filtered fluid is processed to form urine.

5. **Conclusion**: The excretory unit in the human excretory system is called the nephron.

**Final Answer**: The excretory unit in the human excretory system is called the nephron.
