Immune Response
Bodily defense process
This explainer walks through the immune response in plain terms: first-line barriers, innate defenses, adaptive antibodies and T-cells, and why timing and coordination matter when the body faces infection.
- innate immunity
- adaptive immunity
- antibodies
- antigens
- t-cells
Inputs
Pathogen presence detected by pattern recognition receptors.
Process
Innate cells respond rapidly; antigen presentation activates adaptive B and T cells.
Outputs
Neutralization, clearance, and memory cells for faster future response.

Why it matters
Climate Resilience
Climate resilience reduces damage from climate-related hazards and speeds recovery.
Comparison
Mitosis vs Meiosis
Mitosis makes matching cells for growth and repair, while meiosis creates sex cells and introduces genetic variation.
Examples
Osmosis
Osmosis is water diffusion through a semipermeable membrane toward higher solute concentration.
