- 1st we went over the assignments from last day
-sandwich story
-thought lab
-jimmy digestion
-experiment

-did notes
-got notes sheet

This class wasnt that bad. We didnt do a whole lot and i didnt have to worry about homework cause i had all my assignments done. So far the human body stuff sucks and theres a lot of dif things you need to know. Like we learnt the functions of the circulatory system
-waste removal/transport gas, nutrients
-immune system
-blood clotting/healing
-body temp
you need all these to be in homeostasis which is internal balance. Thast all we really learned which wasnt a whole lot so class wasnt all that bad.

This site claims to have amazing fact about the circulatory system. They're not that amazing but i though I'd share.

-One drop of blood contains a half a drop of plasma, 5 MILLION Red Blood Cells, 10 Thousand White Blood Cells and 250 Thousand Platelets.
-You have thousands of miles of blood vessels in your body. "Bill Nye the Science Guy" claims that you could wrap your blood vessels around the equator TWICE!
-Keep your heart healthy...it's going to have to beat about 3 BILLION times during your lifetime!
