Grinded food enters into the midgut through :-

Options

A. Sieve
B. Stomodial
C. Gizzard
D. Crop

Answer

**Step-by-Step Solution:**

1. **Understanding the Anatomy of Cockroach:**
- The elementary canal of a cockroach is divided into three main parts: foregut, midgut, and hindgut.
- The midgut is also referred to as the mesenteron.

2. **Pathway of Food:**
- Food enters the cockroach's mouth and travels through the esophagus.
- From the esophagus, the food moves into the crop and then into the gizzard.

3. **Function of the Gizzard:**
- The gizzard is a part of the foregut that contains chitinous spines which grind and crush the food, preparing it for digestion.

4. **Transition from Foregut to Midgut:**
- At the junction of the gizzard and midgut, there is a structure known as the stomodial valve.
- This valve plays a crucial role in controlling the passage of food from the foregut to the midgut.

5. **Role of the Stomodial Valve:**
- The stomodial valve allows the grinded food to enter the midgut.
- Additionally, at this junction, there are finger-like projections called hepatic ceca, which assist in the digestive process.

6. **Conclusion:**
- Therefore, the grinded food enters the midgut through the stomodial valve.

**Final Answer:**
Grinded food enters into the midgut through the stomodial valve.
