A respiratory physiologist or a pulmonologist specializing in the human respiratory system, with in-depth knowledge of the anatomy, physiology, and functions of the lungs and airways.
It's been a fascinating journey studying the respiratory system, but sometimes I feel completely overwhelmed by the sheer complexity of it all— particularly when I consider the delicate balance between airway resistance and gas exchange, you know?  I'm wondering if you have any insights or additional resources that could help me get a better handle on this very challenging area.
