You Have More to Learn
Unfortunately, you didn't do quite so well on this one. Learning about our respiratory system is something we'd recommend doing more of since this becomes more of a health risk as time goes by. How about reading a bit about it and trying again?
Not Bad!
You know quite a bit about the respiratory system it seems, and the organs it uses to keep us breathing. It's important that we know this system well in order to avoid lung diseases and risk factors, as well as identify problems as they pop up. You still could get a higher score if you wish to try again.
Most Excellent!
You've shown an excellent familiarity with the human respiratory system. We're delighted to hear this because it's such an important system and knowing all about it can really help you avoid lung diseases and risk factors as well as recognize problems as they pop up. Congratulations, you've really ACED THIS QUIZ!
