What to Focus On

  • Immune system distinguishes between 'self' and 'non-self'.
  • Foreign substances trigger immune response.
  • Prevents attack on the body's own cells.
  • First line: Skin and mucous membranes act as barriers.
  • Second line: Phagocytes, inflammation, and fever provide non-specific defence.
  • Third line: Lymphocytes and antibodies provide specific, long-lasting immunity.
  • Bone marrow and thymus are primary lymphoid organs.
  • Spleen, lymph nodes, and MALT are secondary lymphoid organs.
  • B-cells produce antibodies; T-cells mediate cell-based immunity.

Common Mistakes to Avoid

Antibodies kill pathogens directly by attacking them like soldiers.

T-cells produce antibodies.

Innate immunity is weaker than acquired immunity.

Memory Tips
