In cockroaches, digestive juice is secreted by the

Options

A. gizzard
B. Malpighian tubules
C. hepatic caeca
D. oesophagus

Answer

To determine which organ in cockroaches secretes digestive juices, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organ Systems**: Understand that cockroaches belong to the phylum Arthropoda and have a complex digestive system. Familiarize yourself with the different organs involved in digestion.

2. **List the Options**: The options provided are:
- Gizzard
- Malpighian tubules
- Hepatic ceca
- Esophagus

3. **Analyze Each Option**:
- **Gizzard**: This organ is primarily responsible for grinding food, not for secreting digestive juices.
- **Malpighian Tubules**: These are excretory organs in cockroaches, involved in the removal of waste, not digestion.
- **Hepatic Ceca**: This is the correct answer. The hepatic ceca are glandular structures that secrete digestive juices and enzymes necessary for breaking down food.
- **Esophagus**: This organ is involved in the movement of food through peristalsis but does not secrete digestive juices.

4. **Conclusion**: Based on the analysis, the organ responsible for secreting digestive juices in cockroaches is the **Hepatic Ceca**.

### Final Answer:
The digestive juice in cockroaches is secreted by the **Hepatic Ceca**.
