1 How is our body like a planet?

2 We are all very lucky to be here on EARTH!

3 We are all very lucky to be here on EARTH—our HYDROSPHERE!

4 We are all very lucky to be here on EARTH—our HYDROSPHERE!
Water never enters or leaves our hydrosphere…it just changes states

5 Our Earth supports billions of us humans…

6 …and countless other life forms!

7 So, how is OUR BODY like the planet EARTH?

8 What’s these numbers in scientific notation?
Our body consist of 40 to 100 trillion cells (40,000,000,000,000 to 100,000,000,000,000 cells) What’s these numbers in scientific notation?

9 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!

10 BUT THAT’S NOTHING…

11 In your body, BACTERIA ALONE OUTNUMBER your CELLS 10:1!

12 In your body, BACTERIA ALONE OUTNUMBER your CELLS 10:1!
That’s 400 to 1000 TRILLION bacteria in OR on your body RIGHT NOW!

13 In your body, BACTERIA ALONE OUTNUMBER your CELLS 10:1!
That’s 4 x 1014 to 1 x 1015 bacteria in OR on your body RIGHT NOW!

15 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.

17 This image shows the “CITIES” where bacteria live inside & outside our bodies.

18 YOUR BODY IS A PLANET!

19 What are all these inhabitants?

20 MICRO-ORGANISMS = MICROBES

21 MICRO-ORGANISMS = MICROBES
BACTERIA

22 MICRO-ORGANISMS = MICROBES
BACTERIA VIRUSES

23 MICRO-ORGANISMS = MICROBES
BACTERIA VIRUSES PROTOZOA (protists)

24 MICRO-ORGANISMS = MICROBES
BACTERIA VIRUSES PROTOZOA (protists) some FUNGI some PARASITES

27 This image again shows the “CITIES” where BACTERIA live inside & outside our bodies.

28 How do these micro- organisms work together???
This image shows the “CITIES” where bacteria live inside & outside our bodies. How do these micro- organisms work together???

29 How do these micro-organisms protect us???
THEY CAN COMMUNICATE WITH EACH OTHER!!!! Bonnie Bassler Groups of 2-3 do “Your body is a planet” worksheet.

30 end day 1

31 Of course not all microbes are harmless nor helpful!

32 Any DISEASE-CAUSING microbes/micro-organisms have a special name:

33 Any DISEASE-CAUSING microbes/micro-organisms have a special name:
PATHOGENS or CONTAGIONS!

34 Any DISEASE-CAUSING microbes/micro-organisms have a special name:
BAD VIRUSES BAD BACTERIA PATHOGENS or CONTAGIONS aka GERMS!

35 Any DISEASE-CAUSING microbes/micro-organisms have a special name:
BAD VIRUSES BAD BACTERIA BAD FUNGI BAD PROTISTS PATHOGENS or CONTAGIONS aka GERMS!
