Immune System
The cells and tissues of the body that fight invading organisms
Real World Example
Imagine your home as a fortress that you want to keep safe from burglars. The immune system is like the security measures you put in place, such as locks, alarms, and vigilant neighbors, all working together to keep intruders out. Just as these security measures identify and respond to any unauthorized entry in your home, the cells and tissues of your immune system recognize and fight off invading organisms to protect your body.
