Fascila attaches its self to walks of the biles ducts by means of

Options

A. Anterior sucker
B. Adhesive zone
C. Posteror sucker /acetabulum
D. Spiny cuticle and posterior sucker

Answer

To answer the question "Fasciola attaches itself to the walls of the bile ducts by means of," we need to analyze the structure and features of the Fasciola hepatica, commonly known as the liver fluke.

### Step-by-Step Solution:

1. **Identify the Organism**:
- Fasciola hepatica is a type of flatworm, specifically a fluke, and is known for its leaf-shaped body.

2. **Understand the Morphology**:
- The adult Fasciola has a broader anterior end and a narrower posterior end. The anterior end features a cone-shaped projection.

3. **Recognize the Attachment Structures**:
- Fasciola hepatica has two main structures that aid in attachment:
- An **oral sucker** located at the anterior end.
- A **ventral sucker** (also referred to as the posterior sucker) located at the base of the cone.

4. **Function of the Suckers**:
- Both the oral sucker and the ventral sucker are used to attach to the lining of the bile ducts. They create a strong hold, allowing the fluke to remain in place within the host's bile ducts.

5. **Conclusion**:
- Given the options provided (anterior sucker, adhesive zone, posterior sucker, or spiny cuticle), the correct answer is that Fasciola attaches itself to the walls of the bile ducts primarily by means of the **spiny cuticle and the posterior sucker**.

### Final Answer:
Fasciola attaches itself to the walls of the bile ducts by means of **spiny cuticle and posterior sucker**.
