How the immune system works.

every single second of your life you are under attack millions of bacteria virus and funding are trying to make you their home so our bodies have developed a super confusing system to protect you from dying. Its a lovely day until you meet a rusty nail and you cut yourself near by bacteria sees the opportunity and enter the wound they start using the body resource and multiply their number every 20 second once they hit a huge amount they change their behavior and start damaging the body .Your guard cells A.K.A macrophages they are huge sells and can eat up to 100 enemy each the trap it in a membrane and kill it  they send messenger proteins to let the blood flow into the battle field to make fighting easier.Then they send a heavy messenger protein and get neutrophiles for help.Once they fight for too long the brain of the immune system kicks in.The dendritic cell gets active it reacts to the signals from the soldiers.Then it starts collecting samples from the enemies they rip  them into pieces and presents the parts onto the outer layer.it makes a crucial dishion shoud they call for anti bacteria forces that eradicate infected body cell of an army of bacteria killers in this case anti bacteria forces are necessary.It travels to the closest lymph nodein about a day here are billionsof helpers and killer-T cells waiting to be activated.When  T-cells are born they go through a diffucult and complicated training porcess only a quarter survives.The surviving cells are equiped with a specific setup.The dendritic cell is on the way looking for helping T-Cell with a set up thats just right.Its looking for a helper T-cell that combines the parts of the intruders which the  dendritic cell presented on its membrane.When it finally finds one a chain reaction takes place.The helper T-cell is activated.It quickly duplicates thousands of times some become memery T-cells  that stay in the lymph mode and will praticly immune this enemy.Some travel to the feild of battle to help out and the third group goes on to travel to the center of the lymph  node to be activated.A very powerful weapons factory like T-cells they are born with a specific setup.When a B-cell and a T-cell with the same setup meets,hell breaks loose.The B-cell duplicates rapidly and starts producing millions of little weapons they work so hard that they die from exhaustion really fast.Here helper T-cells play another important roll they stimulate the hard- working

factories and tell them “Don't die yet!We still need you keep going!” This also ensures the factories  die if the infection is over,so the body doesn’t hurt himself or waste energy or hurt itself.But what is produced by the B-cells? You’ve heard of them,of course:antibodies.Little proteins that are engineered to bind to the surface or the specific intruder there are even different types of  antibodies that have slightly different jobs.The helper T-cell tell the plasma cells which type is needed the most in this  particular invasion millions of them flood the blood  and saturate the body.
