ImmunoDefense is a fun and challenging way to learn how our defense system (immune system) works, protecting the body against infections. The game is fun and you will understand how our defense barriers work: the cellular barrier; the physical barrier and the physiological barrier. By playing ImmunoDefense you will come into contact with some cells, important characters in our defenses, such as neutrophils and macrophages, which are the cells of our first line of defense. After the physical barriers (skin, mucous membranes, hair), they are responsible for engulfing the pathogen and trying to destroy it. Other cells will join the fight, such as different types of lymphocytes, responsible for our longer-lasting protection against different infectious agents.
