Question

What is the importance of immunity​

Answer 1

Answer:

The main purpose of your immune system is to protect your body from viruses and bacteria. Without it, they’d have free reign and you’d be constantly falling ill. Your immune system works by recognising the difference between your body’s cells and alien cells, allowing it to destroy any that could be potentially harmful. This usually works well but can cause problems if your immune system wrongly classifies some of your own cells and attacks them instead.
