The diagrams below illustrate the inflammatory response that may occur when a pathogen enters the human body: Diagram 1 Due to copyright restrictions, this material is not supplied - VCE - SSCE Biology - Question 21 - 2022 - Paper 1

Based on the information provided in the diagrams and the functions of the immune cell types,

1. Cell 1: Likely a dendritic cell, which plays a role in presenting antigens to T cells.
2. Cell 2: This cell could be a T cell, known for releasing cytokines.
3. Cell 3: Represents a neutrophil, known to act as a phagocyte.
4. Cell 4: This could be a mast cell, which releases histamines during an allergic response.

From the options provided in the question, the correct identification of the cell's role in the inflammatory response is D. neutrophil, as it acts primarily as a phagocyte.
