Normally heamopoiesis in frog occurs in

Options

A. liver and bone marrow
B. liver
C. spleen
D. bone marrow

Answer

**Step-by-Step Solution:**

1. **Understand Hemopoiesis**: Hemopoiesis is the process of blood formation in an organism. It is important to identify where this process occurs in frogs.

2. **Evaluate the Options**: The question provides several options regarding where hemopoiesis occurs in frogs. We need to analyze each option to determine the correct answer.

3. **Option Analysis**:
- **Bone Marrow**: In mammals, bone marrow is the primary site for blood formation. However, in frogs, hemopoiesis does not occur in the bone marrow. Therefore, this option is incorrect.
- **Spleen**: The spleen functions primarily as a filter for blood and is involved in the immune response. It is not a site for blood formation in frogs, making this option also incorrect.
- **Liver**: The liver is known to play a role in blood formation, especially in adult frogs. Additionally, during the embryonic stages, the liver is a crucial organ for hemopoiesis. This suggests that the liver is a correct option.
- **Combination of Liver and Bone Marrow**: While the liver is involved in hemopoiesis, the bone marrow is not relevant for frogs. Therefore, this combined option is misleading and incorrect.

4. **Conclusion**: Based on the analysis, the liver is the primary organ for hemopoiesis in frogs, especially considering both adult and embryonic stages. Thus, the correct answer is the liver.

**Final Answer**: Normally, hemopoiesis in frogs occurs in the liver.
