Now, once the cell lyses we have these macrophages that are also called upon by these cytokines released into our blood as a result of that mast cell and other cells. Now, these macrophages are the largest type of phagocytic cell in our body. They basically move from the blood into our tissue and they begin engulfing anything that is harmful or pathogenic to the healthy cells of our body. And that includes the ly cell that was lies by the natural killer cell or any infected cell or any pathogen found inside our tissue. So macrophages are large phagocytic cells that engulf pathogens infected cells cancer cells and any debris that is found within a tissue that might be harmful to the cells of that tissue. So these move from the blood and into our tissue.
