How is our body like a
planet?
We are all very lucky to be
here on EARTH!
We are all very lucky to be here
on EARTH—our HYDROSPHERE!
We are all very lucky to be here
on EARTH—our HYDROSPHERE!
Water never enters or leaves our
hydrosphere…it just changes states
Our Earth supports billions of
us humans…
…and countless other life forms!
So, how is OUR BODY like the
planet EARTH?
Our body consist of 40 to 100
trillion cells (40,000,000,000,000 to
100,000,000,000,000 cells)
Our body consist of 40 to 100
trillion cells (40,000,000,000,000 to
100,000,000,000,000 cells)
4 x 1013 to 1 x 1014 CELLS in YOU!
BUT THAT’S NOTHING…
In your body,
BACTERIA
ALONE
OUTNUMBER
your CELLS
10:1!

MANY BACTERIA in our bodies
PROTECT our HEALTH!
 Researchers who study the friendly bacteria that live inside all of us
are starting to sort out who is in charge—microbes or people?

By Jennifer Ackerman
 Biologists once thought that human beings were physiological islands,
entirely capable of regulating their own internal workings. Our bodies made
all the enzymes needed for breaking down food and using its nutrients to
power and repair our tissues and organs. Signals from our own tissues
dictated body states such as hunger or satiety. The specialized cells of our
immune system taught themselves how to recognize and attack dangerous
microbes—pathogens—while at the same time sparing our own tissues.
 Over the past 10 years or so, however, researchers have demonstrated that
the human body is not such a neatly self-sufficient island after all. It is more
like a complex ecosystem—a social network—containing trillions of bacteria
and other microorganisms that inhabit our skin, genital areas, mouth and
especially intestines. In fact, most of the cells in the human body are not
human at all. Bacterial cells in the human body outnumber human cells 10 to
one. Moreover, this mixed community of microbial cells and the genes they
contain, collectively known as the microbiome, does not threaten us but
offers vital help with basic body processes—from digestion to growth
to self-defense.
