- Xiphoid process
what 2 bones together form the shoulder girdle and our very important structures and landmarks in anesthesia
clavicle
scapula
what makes up Passive inspiration?
diaphragm (75-80%) external intercostals (remainder)
what makes up Active inspiration?

what are the different divisions of the 23 bronchi? just give me number groups more detail to come!
1-16
17-19
20-23
with the 23 generations of the bronchi what are the 1-16 for?
conduction
with the 23 generations of the bronchi what are the 17-19 for? and what begibs to be present here?
Transition
-alveoli begin to be present here
with the 23 generations of the bronchi what are the 20-23 for? and what is important about the 23rd generation?
respiratory
- “terminal bronchiole” ends in alveolar sac
