1.
The events of respiration are
a)
inhaling and exhaling.
b)
ventilation, external and internal respiration, and cellular respiration.
c)
inflating and deflating alveoli.
d)
delivering carbon dioxide to cells and removing oxygen from cells.
2.
Breathing functions to
a)
deliver oxygen to cells, where it takes part in the reactions of cellular respiration that liberate energy from nutrient molecules and get rid of carbon dioxide, which maintains the pH of the internal environment.
b)
inflate the lungs, which forces oxygen molecules into the bloodstream.
c)
deliver carbon dioxide to cells, where it takes part in the reactions of cellular respiration that liberate energy from nutrient molecules and get rid of oxygen, which maintains the pH of the internal environment.
d)
deliver oxygen to cells, where it takes part in the reactions of cellular respiration that liberate energy from waste molecules.

Arielle is an 8-year-old with cystic fibrosis. For 30 minutes each morning and evening, a parent holds her body in various positions and massages and kneads the areas over her lungs to dislodge the abundant, sticky mucus, which Arielle spits into a jar. She also takes medication - an enzyme - that thins the mucus. If she didn't take these measures, the mucus in her lungs would most likely increase her risk of
a)
cancer
b)
emphysema
c)
infection
d)
asthma
