Bronchi 1. primary bronchus -> secondary (lobar) bronchi 2. secondary bronchi -> tertiary (segmental) bronchi 3. tertiary bronchi -> bronchioles 4. bronchioles -> terminal bronchioles F. Lungs 1. outer pleural membranes (remember balloon analogy) a. parietal pleura - on thoracic cavity wall b. visceral pleura - covers the lungs 2. apex (cupula) - 1 inch superior to the clavicle 3. base - just above the diaphragm 4. costal surfaces - against the ribs 5. mediastinal surface - against the heart 6. hilus - bronchi, vessels, nerves enter and exit 7. cardiac notch - where heart lies near left lung 8.
