Skin prevents microbes from entering your body...
it will reduce the immunity
Good bacteria help in digestion of food and fight microbes invading the body. Bad bacteria can make people sick or spoil food.
white blood cells in the blood
This term is antisepsis. Most of the human body, internally is free of microbes. But not all. The mouth and esophagus have normal microbes as does the upper respiratory tract including the nose. The lower portion of the digestive tract, very low in the urinary tract and the genital tracts there are normal microbes.
The total biomass of microbes is estimated to be significantly greater than that of the human population. Microbes are present in large quantities in various environments such as soil, water, and the human body, contributing to a higher overall biomass compared to humans.
Resident microbes, including bacteria, fungi, and other microorganisms, make up approximately 1-3% of human body mass. While the number of microbial cells in the body is estimated to outnumber human cells by about 10 to 1, their total mass is relatively small compared to the overall body weight. These microbes play crucial roles in digestion, immunity, and overall health.
One way the body protects itself against microbes is with the cell membrane. The cell membrane is like a body guard, it lets certain cells, and virus's in. Another way the body can protect itself is with the white blood cell. The white blood cell defends the body against microbes.

Microbes that make you sick are often referred to as pathogens or harmful bacteria. These microorganisms can cause infections or diseases in the human body.
Now scientists say that at least 10,000 species of bacteria and other microbes inhabit the human body, a lot of them in the large intestine. They also say that almost everyone - even when they're healthy - has pathogenic microbes (those that can cause disease) inside their body. In healthy people these potentially harmful microbes cause no problems. Most microorganisms in the body are bacteria, but yeasts and viruses are also found in the microbiome.hope this help.. :D
