Final answer:
Removing dentures is important when assessing a patient's airway to ensure clear breathing and to prevent obstruction; this is especially true in an unconscious patient. Additionally, the bronchi branch into bronchioles, not vice versa, and gas exchange occurs in the alveoli in the human respiratory system.
Step-by-step explanation:
The statement 'You should remove the patient's dentures when assessing the airway' is generally true. When providing first aid or medical assistance, it's crucial to ensure that the airway is clear. Objects such as teeth or dentures can obstruct the pharynx, impeding breathing or potentially causing choking. Therefore, if a patient is unconscious or unable to respond, removing the dentures is a key step in assessing and securing a clear airway. This action facilitates proper air flow and minimizes the risk of obstruction during evaluation or treatment.
In the human respiratory system, air does indeed travel from the pharynx to the trachea when we breathe in. However, the bronchioles do not branch into bronchi; it's the other way around—the bronchi branch into bronchioles. The bronchioles eventually lead to alveolar ducts, which connect to alveolar sacs where gas exchange takes place.
