They ingest bacteria, foreign cells, and damaged and dead cells. (The process of a cell ingesting a microorganism, another cell, or cell fragments is called phagocytosis, and cells that ingest are called phagocytes.). Macrophages secrete substances that attract other white blood cells to the site of the infection.ytokines are the messengers of the immune system. White blood cells and certain other cells of the immune system produce cytokines when an antigen is detected. There are many different cytokines, which affect different parts of the immune system: Some cytokines stimulate activity.
