How the body deals with “Uninvited Guests”

Every day, we are exposed to countless “uninvited guests” such as bacteria, viruses, fungi or parasites. To protect us, the immune system works like a highly organised defence army, always on guard - from the first line of defence and beyond.

Specialised immune cells patrol the body, recognise potential dangers, and launch a rapid response. They neutralise harmful microbes, remove damaged cells, and remember past encounters to react faster in the future. This remarkable cooperation between different types of immune cells is what keeps us healthy and resilient.

🛡 First line of defence – barriers like skin and mucous membranes stop many microbes at the entrance.

⚔️ Rapid response – immune cells detect invaders, attack them, and reduce their spread.

📚 Immune memory – after each battle, immune cells “remember” the threat, so the next response is faster and stronger.

👉 Together, these 3 steps create a smart, adaptive defence system that works 24/7 to keep us healthy.

We call it the immune system.
