Normal relationship and Size – Arterioles and Bronchioles |
| In this CT of a normal patient we see two levels of the RLL with the segmental bronchioles and arterioles branching dichotomously and simultaneously. Note again the similarity in size and shape through these levels of division, a form that is maintained in the normal person until they reach the terminal bronchiole.
