Question

Why is the immune system essential for our health?

Answer 1

Hint: The immune system is basically a complex network of protective cells and protective proteins that defends the body against all the kinds of infections. The immune system maintains the record of every germ it has ever defeated so it can easily recognize and destroy the microbe quickly if it enters the body again.

Complete Answer:
- Basic introduction about the immune system is already suggested in the hint. Let us now understand why it is important for our health.
- Proper functioning of our immune system will help us to get protected in our daily life as we come in contact with uncountable germs and bugs from pets, other people, and our environment as well.
- Without a healthy immune system, we may pick up infections and infectious diseases more regularly and easily, and the effects of such infection on us can be serious or even fatal. Our body's first line of defense is its physical barriers (that means skin).
- And when it enters inside the body, immune cells immediately come into action to carry out the defensive mechanism. Hence it is important for our health.

Note: Vaccination and immunization is based on the property of the memory of the immune system(special memory T-cells helps to recognize the pathogen).
- If viruses and bacteria manage to break through and enter the skin, there are certain specialized immune cells that immediately come into action.
- Our bloodstream and the other key areas of our body contain white blood cells that can fight and destroy the viruses and bacteria they find.
- Also, they keep it in the records so that when they invade inside the body again our body can directly take action against those foreign pathogens.
