Many of the microbes of the air and food are harmless, but some of them, when they get into the body, produce diseases such as consumption, diphtheria, and typhoid fever. In different parts of the body there are small fleshy organs called glands. The glands act as filters and keep back any microbes of disease which may get into the body. Sometimes when the glands have filtered very many germs they become swollen and inflamed. Thus, when we have a poisoned finger, it is due to a large' number of microbes getting into the wound.
