Final answer:
The claim about correct inhaler use is typically True; during an asthma attack, medication like albuterol helps by widening airways. False statements about the respiratory system include the bronchioles branching into bronchi, and that the lungs do not receive oxygenated blood. Gas exchange only occurs in the alveoli.
Step-by-step explanation:
When using an inhaler, such as an albuterol inhaler for asthma, the recommendation to hold the inhaler 1-2 inches away from the front of the mouth or close your mouth around the mouthpiece is typically True. The container dispenses medication, targeting the back of the throat to ease respiratory conditions like asthma. During an asthma attack, illustrated in a photo and molecular model, airways narrow and may become clogged with mucus, obstructing breathing.
Regarding the human respiratory system, the statement that 'The bronchioles branch into bronchi' is False - it's the other way around, the bronchi branch into bronchioles. Moreover, the False statement that lungs receive oxygenated blood can be misleading; while most blood that reaches the lungs is deoxygenated and needs to be oxygenated through gas exchange, there is indeed a small amount of already oxygenated blood that comes from the bronchial circulation.
Lastly, the statement that gas exchange occurs in both the upper and lower respiratory tracts is False. Gas exchange occurs in the alveoli of the lower respiratory tract, where oxygen is absorbed into the blood and carbon dioxide is expelled from it.
