Verified step by step guidance

Understand the anatomy of the trachea and primary bronchi: The trachea splits into two primary bronchi, the right and left, which lead to the lungs. These bronchi differ in structure and orientation.

Examine the structural differences: The right primary bronchus is wider, shorter, and more vertical compared to the left primary bronchus, which is narrower, longer, and more horizontal.

Consider the implications of these differences: Because the right bronchus is more vertical and wider, objects that are aspirated (inhaled) are more likely to follow the path of least resistance and lodge in the right bronchus.

Relate this to clinical observations: In medical practice, aspirated objects are frequently found in the right bronchus due to its anatomical characteristics.

Conclude based on the anatomical evidence: The correct answer is the right primary bronchus, as its structure makes it the most likely location for aspirated objects to lodge.
