regenerate. The result normal cells are replaced by another type of cell.

What type of cells usually replace normal cells in replacement healing? -

✔✔connective/scar

What can result from replacement healing? - ✔✔decreased function

What are the two healing processes - ✔✔1. First intention (sutured)

- usualy increased to show bacterial infection (left shift)

What are basophils - ✔✔histamine releasing phagocyte

What are Eosinophils - ✔✔phagocytes released in

-Type I allergic

Histamine release

What are the agranulocytes - ✔✔B-Cells

T-Cells

Monocyte-Macrophage

What cells are involved in specific immunity - ✔✔B & T cells
