How Your Immune System Works

The immune system one of the most complex parts of the human body an intricate network of cells and molecules evolved over the course of hundreds of thousands of years to protect us from the dangers of the outside environment so how does it work fast detect a threat summon help and launch a counterattack when a virus infiltrate to sell for example a cell lining our our way the cell detects this as foreign and produce decided to kinds messenger proteins to someone help via fake a cite a type of white blood cell and also help to contain the local spread of the virus from cell to cell typically the role of interferons specialized white blood cells called fake sites tried to destroy the intrusion virus by literally eating them up these first responders show up within minutes and makeup of the innate immune system it is false to respond but not precise and it does it’s best to shut down and its section as soon as possible the adaptive immune system is highly specialized but much slower dendritic cells collect small fragments of the virus left over from the battles of the innate immune system and ferry these two are linked to mood where highly specialized white blood cells t cells awaiting he sells a pre programmed soldiers each one in trained to target a specific invader when a dendritic cell carrying a specific type of virus fragments shows up the relevant t cell will divide many times to produce an army of clones there are two main types of t cells sites are toxic t cells recognise and destroy infected cells that top of the virus and help the t cells boost the immune response by activating be cells to produce antibodies antibodies a specific proteins that look the structures that viruses use to latch onto and then trust them on t voters also i must help to the viruses that are floating around what was that piece sounds and be sounds can take several days to move into action they are incredibly precise and they remember after the virus has been neutralized and the army stands down to most specific t cells and b cells die off but a small fraction stay on that patrolling the bloodstream and lynn mm slides for repeated tax if the same virus attacks out sounds again teased memory cells spring into action activating the power of the adaptive immune systems without the days long start up this memory is the basis of how a childhood infection or vaccination can lead to lifelong protection…read more here
