प्रश्न
Explain how does the body react after the entry of microbe in the body.
उत्तर
When the immune system first encounters an infectious microbe,the immune system of the body gets activated and starts releasing antibodies against the microbes. The immune system comprises several WBCs that fight against the microbes. These cells kill the microbes before they cause much harm to the body and then remembers it specifically. So the next time that particular microbe, or its close relatives enter the body, the immune system responds with greater vigour. This eliminates the infection even more quickly than the first occurrence of the disease.
