1. Read the following passage carefully:

There are a few automatic activities of our body known as 'reflex phenomenon' which protects the body against many infections. This reflex phenomenon includes sneezing, coughing, and vomiting.

Fever is one of the most important constituents of the defence mechanism of our body. The organ which regulates the temperature of our body is known as hypothalamus and is situated in the brain. When micro-organisms after entering the body release toxic products and these reach the brain through blood, the hypothalamus starts increasing the temperature of the body and the person gets fever. This fever is very useful for the human body because due to the increase of temperature, the micro-organisms which are the root cause of the problem get killed.

We are living in an environment which is full of bacteria. Many of these bacteria can produce serious diseases, but all of us do not suffer from such diseases. It is due to a special power present in our body to fight these diseases. A part of this special power of our body is known as innote immunity. This we gain during our lifetime.

In a nutshell, we can say that since nature has provided us with defence mechanism to fight against so many diseases, let us maintain it or rather increase it by the way of immunisation. - Rukesh Singh [The Tribune]
