Storyboard Description

My immune system analogy is about the Alabama football team protecting their national championship trophy from fans trying to take the precious award. The football stadium itself serves as the trophy's mechanical first line of defense, as the skin does on the body. The stadium is on the very outside of everything and is the first thing the fans must enter to get to the trophy, protecting it from any foreign invaders. The fire alarms will next release a toxic mist that will serve as the chemical first line of defense once people have entered the gates of the stadium. For example, stomach acid, it will also targeting any and all foreign invaders. The second line of defense would be the security guards, as they would identify the invaders and prevent them from getting to the trophy. In the body, phagocytes identify the foreign pathogen and quickly rush to it to contain it. The third line of defense would be the coaches and players. The coaches being the antigens that are capable of stimulating an immune response, and the players being the antibodies. White blood cells called lymphocytes carry a specific type of antibody that have a chemical fit, specifically attacking pathogens that break past the first and second lines of defense. The coaches would inform the players and the players would immediately attack the fan near the trophy.
