  • What is one way pathogens evade the immune system?
    Pathogens can evade the immune system by hiding within host cells.
  • How does hiding inside host cells protect pathogens?
    It protects pathogens from antibodies and phagocytic cells like macrophages.
  • What type of immune cell tries to phagocytose pathogens?
    Macrophages are phagocytic cells that try to phagocytose pathogens.
  • What happens when a pathogen hides inside a host cell?
    The macrophage cannot find or destroy the pathogen once it is inside a host cell.
  • Why does the pathogen feel safe inside the host cell?
    Because it is protected from immune detection and destruction.
  • What is the cartoon illustration used to explain?
    It explains the interaction between a bacterial pathogen, a macrophage, and a host cell.
  • What does the macrophage say when it cannot find the pathogen?
    The macrophage says, 'Where did that microbe go?'
  • What is the main benefit for pathogens hiding within host cells?
    The main benefit is evading the immune system and causing disease.
  • What are antibodies unable to do when pathogens hide in host cells?
    Antibodies are unable to detect or neutralize pathogens inside host cells.
  • What is the role of phagocytic cells in the immune system?
    Phagocytic cells, like macrophages, engulf and destroy pathogens.
  • How do pathogens cause disease by hiding in host cells?
    They avoid immune detection, allowing them to survive and multiply.
  • What evolutionary advantage do pathogens gain by hiding in host cells?
    They gain the ability to evade host defenses and persist in the body.
  • What is the focus of the lesson video?
    The focus is on how pathogens hide within host cells to evade the immune system.
  • What will future lessons provide regarding this topic?
    Future lessons will provide practice applying these concepts.
  • What is the significance of the host cell in pathogen evasion?
    The host cell acts as a protective environment for the pathogen against immune attacks.
