IB Biology Topic C3.2.4 Differences Between the Innate Immune System and the Adaptive Immune System Revision Notes (SL/HL) | RevisionDojo

Written by official IB examiners

Innate Immunity Is Fast and General, Adaptive Immunity Is Slow but Specific

The immune system protects the body from pathogens like bacteria and viruses.
It has two parts: the innate immune system and the adaptive immune system.
They work together but in fundamentally different ways.

Analogy

The innate system is like the castle wall, broad and immediate.
The adaptive system is like the elite guards, specific and strategic.

The Innate System Responds Immediately to Any Pathogen

Definition

Innate immune system

A general, non-specific response that does not change throughout life. It responds quickly to pathogens in a broad and generalized way

Key Features of the Innate System

Non-specific: it targets broad categories of pathogens, not particular strains.
No memory: the response is the same however many times a pathogen is met.
Rapid: it acts within hours, buying time while the adaptive system gears up.
Present from birth: it is ready to work without any prior exposure.
