Final answer:
Children have narrower airways, less-developed cartilage, higher proportion of smooth muscle, and fewer small bronchioles compared to adults.
Step-by-step explanation:
There are four ways in which the airway anatomy is different in children compared to adults:
- Children have narrower airways compared to adults, which makes them more susceptible to airway obstruction.
- Children have less-developed cartilage in their airways, making them more prone to collapse.
- Children have a higher proportion of smooth muscle in their airways, which makes them more reactive and prone to bronchospasms.
- Children have fewer small bronchioles, which reduces their ability to expel mucus and foreign particles effectively.
