Inner layer of Bowman's capsule consists of

Options

A. podocytes
B. nephridia
C. osteocytes
D. choanocytes

Answer

### Step-by-Step Solution:

1. **Understanding Bowman's Capsule**: Bowman's capsule is a crucial part of the nephron in the kidney, serving as a filtration unit for blood.

2. **Layers of Bowman's Capsule**: Bowman's capsule consists of two layers:
- **Outer Parietal Layer**: This layer is made up of simple squamous epithelial cells.
- **Inner Visceral Layer**: This layer is directly involved in the filtration process.

3. **Identifying the Inner Layer**: The inner layer of Bowman's capsule is known as the visceral layer. It is specifically composed of specialized cells.

4. **Podocyte Cells**: The inner visceral layer consists of **podocyte cells**. These cells have foot-like extensions that create filtration slits, allowing for the selective passage of substances from the blood into the Bowman's space.

5. **Filtration Mechanism**: The spaces between the podocyte cells are called slit pores, which are approximately 25 nanometers wide. These slit pores play a crucial role in the filtration process.

6. **Conclusion**: Therefore, the inner layer of Bowman's capsule consists of **podocyte cells**.

### Final Answer:
The inner layer of Bowman's capsule consists of **podocyte cells**.
