Question

Which of these is the correct order through which oxygen enters the body?



A. lungs, bronchi, bronchioles, alveoli, blood


B. bronchi, lungs, bronchioles, alveoli, blood


C. lungs, bronchi, bronchioles, blood, alveoli


D. blood, alveoli, lungs, bronchi, bronchioles
I thought it was A but that was wrong now i think it might be B ?? PLEASE HELP

Answer 1

i think it's B too

Answer 2

The bronchi are the airways that enter the lungs, so i'd say B
Also the bronchioles lead to the alveoli in which diffusion of oxigen into the blood occurs.
