What occurs during an asthma attack?

• smooth muscle surrounding bronchi remain contracted

• linings of the airway become inflamed

• all of these

What is a good blood oxygen reading?

• 70%

• 80%

• 90%

• 100%

Why are the walls of alveoli so thin?

• so they can inflate easier

• to allow for gas exchange

• so breathing is easier

• so water can diffuse more easily
