Scavenger cell of connective tissue proper is called as-

Options

A. Fibroblast cell
B. Mast cell
C. Plasma cell
D. Macrophages

Answer

**Step-by-Step Text Solution:**

1. **Understanding Connective Tissue Proper**: Connective tissue proper is a type of tissue derived from the mesoderm layer of the embryo. It consists of three main components: matrix, cells, and fibers.

2. **Identifying the Cells in Connective Tissue**: There are various types of cells present in connective tissue, including fibroblasts, mast cells, macrophages, chromatophores, and mesenchyme cells.

3. **Defining Scavenger Cells**: Scavenger cells are specialized cells that play a crucial role in the immune response by ingesting and eliminating waste materials, bacteria, and foreign substances that enter the connective tissue.

4. **Recognizing the Role of Macrophages**: Among the cells mentioned, macrophages are specifically known as scavenger cells. They are derived from monocytes and are responsible for phagocytosing (ingesting) cell debris and pathogens.

5. **Conclusion**: Therefore, the scavenger cell of connective tissue proper is called macrophages.

**Final Answer**: Macrophages.
