This week we continue looking at the Human Body. Remember, as we go through this entire unit, add to, redo, edit your Human Body Notebook 10 projects. Send it to hoopmanscience@gmail.com. This week as a class we are editing and adding to the pages on the circulatory system.
How does the circulatory system move nutrients and wastes?
How are the nturients delivered to cells that need them?
Contracts for this week focus on these questions. Use the Human Body Google Doc we created as a list of resources to use in your research and use this form to add new resources.

Waste and nutrients are in our blood and our blood circulates through our body.
^Oxygen poor blood goes to lungs-get Oxygen & release CO2-in aveoli
^Blood-back to heart and to aorta and other arteries
^through capillaries-Oxygen & nutrients through walls to tissue & waste Ex:CO2 from tissue to veins
^ to heart & back to lungs=CO2 dropped off & Oxygen picked up
This may be math, but if there is 60,000 miles of veins and it takes 2 minutes then how fast is the blood traveling?
Is the 60,000 miles of veins really veins or are they all the arteries and other parts too?

Your kidneys filter the wastes out of the blood and your blood cells also take carbon dioxide to the lungs then you exhale the carbon dioxide out.

Noah, adult humans have about 20 to 30 trillion red blood cells at any time.
did you know gravity helps push blood throughout the body and that capularies connect viens and arteries
what would happen if one side of your heart didnt work
If you have high blood pressure the cells weaken becuse of the force. If you have low Blood there is not eough oxgen getting to the cells.
How many times does your heart beat in a minute?
myles they are veins and arteries and the pice that conests the veins to the arteries too
Austen, the human heart beats 70 to 90 times in a minute when at rest on average but it depends on the person.
how does our body make blood in our bones? And are there like viens in your bones so the blood that is made in your bone marrow can get into your blood stream?
