5. Figure 12-4 diagrams the events involved in the inflammatory response. Assume the following events have
already occurred: tissue injury and invasion of microbes, and release of inflammatory chemicals by mast cells.
Each subsequent is represented by a square with one or more arrows. From the list below, write the correct
number in each even square in the figure. Then, color-code the structures that appear below the numbered
list.
1. WBCs are drawn to the injured area by the release of inflammatory chemicals
2. Tissue repair occurs
3. Local blood vessels dilate, and the capillaries become engorged with blood.
4. Phagocytosis of microbes occurs.
5. Fluid containing clotting protins is lost from the bloodstream and enters the injured
tissue area.
6. Diapedesis occurs
Identify the following in the figure:
monocyte, epithelium, erythrocyte(s),
neutrophil(s), macrophage, subcutaneous
tissue, endothelium capillary,
microorganisms, fibrous tissue repair.
