Filtration of the blood takes place at

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of the Nephron:**
- The nephron is the functional unit of the kidney, consisting of several parts including the Bowman’s capsule, proximal convoluted tubule (PCT), Henle’s loop, distal convoluted tubule (DCT), and collecting duct.

2. **Identifying the Filtration Site:**
- The filtration of blood primarily occurs in the Bowman’s capsule, which is a cup-like structure that encases a network of capillaries known as the glomerulus.

3. **Role of the Glomerulus:**
- The glomerulus receives blood from the afferent arteriole and is responsible for the process of ultrafiltration. Here, blood pressure forces water, ions, and small molecules out of the blood and into the Bowman’s capsule, forming a filtrate.

4. **Understanding the Malpighian Body:**
- The Malpighian body is the collective term for the Bowman’s capsule and the glomerulus. It is the site where the initial filtration of blood occurs.

5. **Conclusion:**
- Therefore, the filtration of blood takes place at the Malpighian body, which includes both the Bowman’s capsule and the glomerulus.

**Final Answer:**
The filtration of blood takes place at the Malpighian body (Bowman’s capsule and glomerulus).
