An immune system is not only one part but a combination of tissues, organs ,and cells some of which is lymphatic nodes , limp vessels , lymphocytes , white blood cells , bone marrow, skin ...

That join to protect you and keep you alive . White blood cells, also called leukocytes . Which play an important roll , in the immune system by continuously Scanning tissues and organs for any suspicious signs . as soon as a foreign substance called antigenes cut your first layer of defence which is the skin , and enters our body . It quickly begins to use your vital resources and starts to double up in number with in a few minutes , it can change your body environment . When the white blood cells detect it malicious activity within minutes, your bodes immune response get activated. It has to relay of leukocytes to tackle it. Which are classified into 2 main groups called phagocytes and lymphocytes . First lymphocytes trigger the immune system response and sent's an army called macrophages and dendeitic cells to enter the blood cell and chew up unwanted thing While eating the they sent information to the phagocytes that time the go on search for a part of the body were infection is there then they go destroy it. B lymphosites use the information gathered from antigens and start to produce a special kind of protein called antibodies. These proteins lock in to specific antigenes and destroy it . The B cells continue to build till all the antigenes are destroyed they do it with a little help of T cells.
