AI Generated Solution

The correct Answer is:
To solve the question "The precursor of tissue macrophages are," we need to analyze the provided options and understand the role of each type of cell mentioned. ### Step-by-Step Solution: 1. **Understanding the Options**: - **Lymphocytes**: These are a type of white blood cell involved in the immune response. They are not the precursors of macrophages. - **Eosinophils**: These are also a type of white blood cell that primarily deals with parasitic infections and allergic reactions. They do not give rise to macrophages. - **Monocytes**: These are a type of white blood cell that is produced in the bone marrow. They circulate in the bloodstream and can differentiate into macrophages when they migrate into tissues. - **None of these**: This option suggests that none of the previous options are correct. 2. **Identifying the Correct Precursor**: - Among the options, monocytes are known to be the precursors of tissue macrophages. When monocytes leave the bloodstream and enter tissues, they differentiate into macrophages. 3. **Conclusion**: - The correct answer to the question is **monocytes**, as they are the direct precursors to tissue macrophages. ### Final Answer: **Monocytes**
