step 1
First exposure to a pathogen -
step 2
a white blood cell called a macrophage consumes the pathogen and displays it's antigen -
step 3
Antigen exposure activates helper T-Cells. Helper T Cells activates B-Cells killer T Cells and create memory T Cells -
step 4
Plasma cells produce and release antibodies -
step 5
Memory b cells recognize a particular pathogen if it returns and rapidly creates plasma cells -
step 6
Killer T-Cells hunt body cells that are infected and kill those cells -
step 7
Suppressor t cells inhibit (stop) cell mediated immune response once the infection is under control -
step 8
Memory t cells recognize particular pathogens if it returns and rapidly creates killer t cells
