Answer

To answer the question "The type of WBC that has nucleus with irregular lobes secretes," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of WBC**:
- The question mentions a type of white blood cell (WBC) with a nucleus that has irregular lobes. This description fits **basophils** or **eosinophils**, which are types of granulocytes.

2. **Understand the Function of These WBCs**:
- Basophils and eosinophils play a role in the immune response. They are involved in allergic reactions and the response to parasitic infections.

3. **Determine What They Secrete**:
- Basophils secrete **histamine**, which is involved in inflammatory responses and allergic reactions. They also secrete **heparin**, an anticoagulant that prevents blood clotting.
- Eosinophils primarily secrete substances that combat parasites and are involved in allergic reactions, but they do not secrete heparin.

4. **Evaluate the Options**:
- The options given are:
- OSN
- Erythropoietin
- Heparin
- Histamine
- Plasma
- Since we established that the WBCs in question secrete heparin and histamine, we can conclude that both of these are correct.

5. **Select the Correct Answer**:
- The correct answer to the question is **heparin and histamine**.

### Final Answer:
The type of WBC that has a nucleus with irregular lobes secretes **heparin and histamine**.
