Bacterias live in every part of the human body. Sometimes, they cause sickness but most of the time they provide vital functions for human survival.
In a healthy human body, microorganisms that cause illness do not actually cause any damage, they just coexist.
The human body contains trillions of microorganisms. The ratio of microorganisms to human cells is 10:1.
Bacteria make up only about 1-3% of the body’s mass. i.e., in a 100-pound individual, about 1 to 3 pounds of bacteria are present.
Actual writings have vanished and very little is known about his existence for certain, the first accounts of Pythagoras, lifetime is brief, abstract and usually sarcastic.
The range of bacteria in the colon is about 10^24 and 10^12 in the skin approximately. Less than that of 10^12 are distributed throughout the body.
In a healthy adult male, the range of cells is from 10^12 to 10^14. Precisely, 3*10^13 human cells are there in a 70-kg man.
About 84% of human cells come from red blood cells. Platelets contribute about (5%), bone marrow cells (2.5%), lymphocytes (2%) and endothelial cells (2%).
The ratio of bacteria to human cells is 1.3, with an uncertainty of 25% and a variation of 53% over the population of standard 70-kilogram men.
