Storyboard Text

  • "Sorry for coughing, i'm a little bit sick".
  • "That's alright the first line of defense will take care of it"
  • "I'm going to get her"
  • "I am here to infect your body"- Pathogen
  • "Not if i have anything to do with it"- Barrier/skin
  • "i'm here too"- Tears
  • Yeah i don't feel good, the pathogen must have gotten into my body.
  • Oh my gosh, you don't look too good.
  • This scene above shows when the first line of defense is triggered. The bodies 1st line of defense uses barriers of the body to prevent pathogens from entering the body and potentiality causing harm. A pathogen can cause an infectious disease, an example of a pathogen is the corona virus.
  • The first line of defense utilizes both physical and chemical barriers, to either stop or kill pathogens attempting to enter the body. The physical barrier includes; skin, mucus, and cilia. The chemical barrier includes tears, saliva, mucus, and stomach acid. The first line of defense acts swiftly but if it fails to prevent the pathogen from entering the body the second line of defense is called into action .
  • There is 3 lines of defense in the body, once the first line of defense fails to keep the pathogen out, the second takes action. The second line of defense of the body is the bodies general response to infection, its main role is to respond to the pathogen that has entered the body, the second line of defense treats all pathogens equal and has the same response to each of them.
  • I feel so much better no my third line of defense can remember the pathogen.
  • The second line of defense occurs after the first line of defense fails to prevent the pathogen from entering the body. The second line of defense uses fever, inflammation and red blood cells named phagocytes to eradicate the pathogen that may cause harm.
  • The third line of defense's role is to identify and destroy pathogens and to also create immunity towards the pathogen. The body uses white blood cells named b-cells in order to identify the pathogen. Antigens trigger b-cell creates a product called antibodies to latch onto the pathogen.
  • After the antibody has found its match it begins to attack and destroy the pathogen. Once the pathogen is destroyed the body leaves b-cell that remain as memory cells, so next time the same pathogen enters the body it is eradicated within minutes.
