ImmunoDefense, a fun and challenging way to learn how our defense system (immune system) works, which works to protect the body against infections. The game is fun and you will be able to understand how our defense barriers work: the cellular barrier; the physical barrier and the physiological barrier. When 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 encompassing 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.
