Answer:
Explanation:
1. Which chamber receives blood from all the body veins?
= Right atrium
2. The blood passes from this chamber into the ...
= Right ventricle
While this is happening, the valve between the right atrium and right ventricle is (open OR closed)
= open
3. The blood in the right ventricle is high in (oxygen OR carbon dioxide)
= carbon dioxide
4. The body (can OR cannot) and low in (oxygen OR carbon dioxide) use this blood.
= cannot
= oxygen
5. Where must this blood go to get a fresh supply of oxygen?
= lungs
Hope this helps!
A process in which something passes by degrees to a different stage (example: plants, animals, humans, etc)
Molecules that cannot cross the membrane bind to receptors in the membrane. When the signal binds to a receptor changes it's shape. Other Molecules inside the cell respond to the chainging shape of the receptor.
