Innate immunity is the body's rapid, first line of defense against harmful invaders.
Understanding Innate Immunity
According to the NCI Dictionary of Cancer Terms, innate immunity represents the first response of the body's immune system to a harmful foreign substance. This means it's the initial way your body reacts when something potentially dangerous enters it.
When substances that don't belong, such as bacteria or viruses, enter the body, certain cells in the immune system can quickly respond and try to destroy them. This response is immediate and non-specific, acting as a general protective barrier and initial counterattack mechanism.
Key Characteristics (Based on the Reference)
- First Response: It's the very first part of the immune system to react.
- Target: Harmful foreign substances like bacteria and viruses.
- Speed: Cells respond quickly.
- Action: Immune cells try to destroy the foreign substances.
This fundamental defense system is always ready to act, providing crucial protection from the moment a threat is detected.
