Now, another type of phagocytic cell that is recruited in this process of inflammation are macrophages. And macrophages come from lymphocytes. So from a specific type of lymphocyte known as monocide. Now, macrophages are the largest type of white blood cell. They're much larger than neutrophils and that's exactly why they can actually engulf and break down about 100 bacterial cells before they actually die off and become pus. Now, the last type of cell that I'd like to discuss but I should note that is not actually part of the inflammation process directly is a cell known as the natural killer cell.
