    • Passive immunity produces memory cells.
      False
    • Give an example of natural active immunity.
      Recovering from measles
    • Steps involved in developing artificial active immunity through vaccination
      1️⃣ Introduction of antigens
      2️⃣ Activation of immune cells
      3️⃣ Antibody production
      4️⃣ Formation of memory cells
    • IgA antibodies are found in breast milk.
    • Artificial passive immunity is acquired through immunoglobulin injections or serum transfer
    • What is the primary purpose of artificial passive immunity?
      Immediate protection
    • Match the condition with its treatment using artificial passive immunity:
      Tetanus ↔️ Tetanus antitoxin
      Snake bite ↔️ Anti-venom
    • What is the definition of immunity?
      Resistance to disease
    • Adaptive immunity creates memory cells that enable a quicker and stronger response upon future encounters with the same antigen.
    • Active immunity provides immediate and long-term protection.
    • What is the main difference between active and passive immunity?
      Memory cells are present in active immunity only
    • Match the source of immunity with the type of immunity:
      Body's own immune response ↔️ Active immunity
      External source ↔️ Passive immunity
    • Order the characteristics of active immunity:
      1️⃣ Body's immune response
      2️⃣ Production of memory cells
      3️⃣ Long-term immunity
    • Passive immunity is always induced by vaccination.
      False
    • In passive immunity, memory cells are absent.
    • What is an example of active immunity?
      Vaccination
    • A newborn baby receives passive immunity from its mother's antibodies.
    • A person who contracts an infection develops natural active immunity.
    • Active immunity results in the production of memory cells
    • Passive immunity provides long-term protection against pathogens.
      False
    • Match the type of immunity with its source:
      Active immunity ↔️ Body's immune response
      Passive immunity ↔️ External source
    • A newborn baby receives passive immunity from its mother's antibodies
    • What is the primary function of immunity?
      Long-term resistance to disease
    • Steps involved in the immune response when an antigen enters the body
      1️⃣ Immune cells identify and target the antigen
      2️⃣ Innate or adaptive response is initiated
      3️⃣ Memory cells are created
    • Passive immunity involves the body producing its own antibodies.
      False
    • Breastfeeding infants receive passive immunity from their mother's antibodies
    • What is natural active immunity developed through?
      Natural infection
    • Recovering from measles provides natural active immunity.
    • How is artificial active immunity developed?
      Vaccination
    • The source of exposure in artificial active immunity is vaccination
    • Match the type of antibody transfer with its source:
      IgG ↔️ Placenta
      IgA ↔️ Breast milk
    • What type of immunity does a newborn baby acquire through breast milk?
      Natural passive immunity
    • Passive immunity provides protection through the transfer of pre-formed antibodies
