Final answer:
Children develop hypoxemia and tissue hypoxia more quickly than adults primarily because of their c)smaller airways, which can lead to increased airway resistance and reduced airflow.
Step-by-step explanation:
Children develop hypoxemia and tissue hypoxia more quickly than adults due to c) Smaller airways. This is because smaller airways can lead to increased airway resistance and reduced airflow.
Especially during respiratory infections or inflammatory conditions, making it more difficult for the child to maintain adequate oxygen levels.
Additionally, children have a higher metabolic rate which demands more oxygen, but the primary reason for their quicker development of hypoxemia is the smaller size of their airways compared to adults.
