How the Immune System Works: A Step-by-Step Guide
Your immune system is your body’s defense mechanism against harmful invaders. Understanding how it works can help you stay healthier and make informed lifestyle choices. Below, explore each phase of the immune response in an easy-to-understand accordion format.
1. Detection
The immune system detects foreign invaders such as viruses, bacteria, and toxins through specialized cells that recognize pathogen-associated molecules.
2. Alert
Once a threat is detected, immune cells release signaling molecules called cytokines to alert and recruit other immune cells to the site of infection or injury.
3. Mobilize
The body mobilizes white blood cells, such as macrophages and neutrophils, to travel through the bloodstream to the affected area.
4. Attack
Immune cells directly attack and destroy the invading pathogens using various mechanisms, including engulfing them or producing antibodies.
5. Resolution
After the infection is under control, the immune system calms down the response, clearing out dead cells and promoting tissue repair.
6. Memory
Some immune cells become memory cells, which remember the pathogen and respond more quickly and effectively if it invades again.
