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.
