Protect the body from germs and diseases
It allows humans to produce offsprings

What if your heart stopped beating for 10 seconds?
If your heart stopped beating for 10 seconds, your brain wouldn’t get enough oxygen-rich blood, and you’d likely pass out! Your body relies on a constant flow of oxygen and nutrients, and without it, cells begin to shut down. If the heart doesn’t restart quickly, serious damage can happen. This is why CPR and defibrillators are used in emergencies—to help restart the heart and keep blood flowing until medical help arrives!
What if… your brain couldn’t send signals to your muscles?
If your brain couldn’t send signals to your muscles, you wouldn’t be able to move! The nervous system works like a messaging system, sending signals from your brain through your spinal cord and nerves to tell your muscles what to do. Without these signals, even simple tasks like walking, talking, or picking something up would be impossible. This is why conditions like paralysis, where nerve signals can’t reach muscles, can have such a big impact on movement!
Major parts of this system include the kidneys and ureters
Excretory System
Body system responsible for maintaining homeostasis
ALL systems work together to keep our body balanced and healthy
