Solution
The correct path for incoming air flow is "segmental bronchi to lobar bronchi".
Here's why:
- Air first enters the body through the nose or mouth, then travels down the trachea.
- The trachea splits into two bronchi (right and left), each leading to a lung.
- Within the lungs, these bronchi further divide into lobar bronchi (three on the right lung and two on the left lung), each supplying a different lobe of the lung.
- The lobar bronchi further divide into segmental bronchi, each supplying a specific segment within the lobes.
- The segmental bronchi continue to divide into smaller and smaller bronchioles, including terminal bronchioles and intralobular bronchioles.
So, the proper path for incoming air flow is from larger to smaller airways, which means from segmental bronchi to lobar bronchi.
