Bacteria is part of our environment, the human body, and is therefore closely linked to our survival.
Bacteria is ubiquitous; in the air, the soil, in the human body, in animal's bodies as well as in vegetables and on their surfaces.. The great majority live in harmony with man and are therefore indispensable to his survival. For example, intestinal bacteria break down nutrients so that they can be absorbed into the bloodstream. These nutrients are unable to break down on their own. Bacteria also provides us with vitamins and protects us against pathogenic bacteria. Moreover, bacteria plays an essential role in our immune system and allows newborns to develop.
Bacteria are much smaller than the cells that compose the human organism and are much more numerous. Whereas human cells number about 10,000 billion, the number of bacteria is ten times greater. A large number of these bacteria are found in the intestines. Several of these bacteria are listed below:
MOUTH - NOSE: 1 billion
