Phagocytic cells present in the tissues

Options

A. Neutrophils
B. Monocytes
C. Macrophages
D. Lymphocytes

Answer

**Step-by-Step Solution:**

1. **Understanding Phagocytic Cells**: Phagocytic cells are a type of immune cell that can engulf and digest cellular debris, pathogens, and dead cells. They play a crucial role in the immune response.

2. **Identifying Types of Phagocytic Cells**: The main types of phagocytic cells include neutrophils and monocytes. Neutrophils are the most abundant type of white blood cells and are typically the first responders to sites of infection. Monocytes, on the other hand, circulate in the bloodstream and can migrate into tissues.

3. **Location of Phagocytic Cells**: Neutrophils are primarily found in the bloodstream and can move to tissues during an immune response. Monocytes also circulate in the blood but can differentiate into macrophages once they enter tissues.

4. **Monocytes in Tissues**: Monocytes are known to migrate from the bloodstream into tissues where they can differentiate into macrophages, which are also phagocytic cells. Macrophages are found in various tissues and are important for cleaning up dead cells and pathogens.

5. **Conclusion**: Among the options provided (neutrophils, monocytes, macrophages, and lymphocytes), the phagocytic cells that are specifically present in tissues are monocytes, as they can enter tissues and differentiate into macrophages.

**Final Answer**: The phagocytic cells present in tissues are **monocytes**.
