Hel As an airplane rises through the atmosphere, machines cause the pressure inside the
cabin to decrease. Based on your observations from the Can Crush Lab, why is this
change in pressure necessary?
A. Air pressure inside the plane should match the air pressure outside the plane.
B. Air pressure outside the plane should be more than the air pressure inside the
plane.
C. Air pressure outside the plane should be less than the air pressure inside the
plane.
D. Air pressure inside the plane should be less than the air pressure outside the
plane.

What is the difference between the conducting zone and the respiratory zone of the respiratory system? the conducting zone is a series of cavities and tubes that move air to the respiratory zone where gases exchange with the bloodstream. the conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone. the conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells. the conducting zone moves oxygen into the bloodstream and the respiratory zone takes carbon dioxide away from the bloodstream.
