Learn the idea
Innate
Innate defenses include barriers and rapid broad responses.
Adaptive
Adaptive responses include antigen-specific recognition and immune memory.
Antibodies
Antibodies bind particular molecular features; they do not replace every immune mechanism.
Limits
This is a conceptual study guide, not advice about diagnosis, medication or vaccination decisions.
Explain without looking
- Why is it important to distinguish a mechanism explanation from treatment advice?
