Final answer:
Based on the position of the bronchi, it would be equally likely for a small aspirated toy to enter the right bronchus or the left bronchus.
Step-by-step explanation:
In the respiratory system, the bronchi divide into smaller and smaller passages called bronchioles. The toy would enter the bronchus that leads to the lung that is most anatomically aligned with the position it enters the respiratory system. Therefore, based on the position of the bronchi, it would be easier for a small aspirated toy to enter either the right bronchus or the left bronchus. Both bronchi are equally likely to be entered by an aspirated toy.
