Why is immune system essential for our health?
Answer:
The immune system of our body is a defence mechanism to fight against pathogenic microbes. It has cells that are specialised to kill infecting microbes and keep our body healthy. If the body’s immune system is strong, it can easily fight pathogens, keeping us healthy.
