Filtration of the blood takes place at

Options

A. PCT
B. DCT
C. Collecting ducts
D. Malpighian body

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where the filtration of blood takes place in the kidney.

2. **Identifying the Options**: The options provided are:
- PCT (Proximal Convoluted Tubule)
- DCT (Distal Convoluted Tubule)
- Collecting Duct
- Malpighian Body

3. **Analyzing Each Option**:
- **PCT**: This is primarily involved in the reabsorption of nutrients, salts, and water, but not in the initial filtration of blood.
- **DCT**: This segment also plays a role in the reabsorption of sodium and water and the secretion of certain ions, but it does not filter blood.
- **Collecting Duct**: This structure is responsible for the reabsorption of water and the concentration of urine, but it does not filter blood.
- **Malpighian Body**: This is also known as the renal corpuscle, which consists of the glomerulus and Bowman's capsule. This is where the filtration of blood occurs.

4. **Conclusion**: The filtration of blood takes place at the Malpighian body (glomerulus and Bowman's capsule).

5. **Final Answer**: Therefore, the correct answer is the Malpighian body.
