  • Antibodies are produced from which cells?
    Antibodies are produced by B cells, which are a type of lymphocyte involved in adaptive immunity.
  • Which blood cells are responsible for fighting infections?
    White blood cells, or leukocytes, are responsible for fighting infections.
  • Which type of cell directly attacks infected cells?
    Cytotoxic T cells directly attack infected cells.
  • Which cell type is not an antigen-presenting cell (APC)?
    Neutrophils
  • How do cytotoxic cells directly attack target cells?
    Cytotoxic cells attack target cells by releasing perforin and granzymes that induce apoptosis in the infected cells.
  • Which specialized leukocytes patrol the body searching for antigens that produce infections?
    Natural killer cells patrol the body searching for antigens that produce infections.
  • Which cell type is an antigen-presenting cell?
    Macrophages
  • What is the function of lymphocytes?
    Immune response
  • Which function is not performed by macrophages?
    Antibody production
  • What is a function of lymphocytes?
    Immune response
  • Bacterial PAMPs are recognized by which cells?
    Bacterial PAMPs are recognized by sentinel cells, such as macrophages and dendritic cells.
  • Which of these cells do not have a role in cell-mediated immunity? Options: A) T cells B) B cells C) Natural killer cells D) Macrophages
    B) B cells
  • Which statement about NK cells is incorrect?
    They produce antibodies
  • What cell types are primarily responsible for immunity?
    Lymphocytes, including T cells, B cells, and natural killer cells, are primarily responsible for immunity.
  • What type of cell is an antigen-presenting cell?
    Macrophages
  • Which cells are involved in both cellular and humoral reactions during an immune response?
    T cells and B cells are involved in both cellular and humoral reactions during an immune response.
  • Which type of white blood cell attacks larger parasites?
    Eosinophils attack larger parasites.
  • Which cell type is essential to the immune response?
    Lymphocytes, including T cells, B cells, and natural killer cells, are essential to the immune response.
  • White blood cells engulf bacteria through what process?
    White blood cells engulf bacteria through the process of phagocytosis.
  • Which cell type is not an antigen-presenting cell?
    Neutrophils
