|
root of lung
(location, contents) |
covered by sleeve of mediastinal pleura
attach lung to mediastinum -pulm artery -2 pulm veins -main bronchus -bronchial vessels -nerves -lymphatics |
|
|
hilum
|
"bare" area of lung outline by reflection of visceral pleura off lung and onto root
|
|
|
right lung lobes/fissures
|
3 lobes: superior, middle, inferior (10 segments)
2 fissures: oblique (between inferior lobe & superior/middle lobes), horizontal (between superior & middle lobes) |
|
|
left lung lobes/fissures
|
2 lobes: superior (w/ lingual), inferior (8 segments)
1 fissure: oblique |
|
|
bronchial tree (pathway of air)
|
trachea
main bronchus lobar bronchus segmental bronchus bronchioles |
|
|
bronchopulmonary segments
|
area of lung supplied by segmental bronchus & accompnaying pulmonary artery branch
smallest functionally independent region of lung each segment receives own airway & artery w/ veins located b/t segments R lung: 10 L lung: 8 |
|
|
pulmonary arteries
|
branches of pulmonary trunk carrying deoxy blood from heart to lung
|
|
|
pulmonary veins
|
carry oxy blood from lungs to heart
|
|
|
bronchial arteries
|
nutritive vascular system of pulm tissues: bronchial walls, glands, large vessels, visceral pleura (aka parenchyma)
branches of aorta and posterioer ICs |
|
|
bronchial veins
|
drain parenchyma into azygos system
|
|
|
pulmonary plexus innervation
|
sym & parasym at bifurcation of trachea distributed along branches of airway/vessels
sym: visceral motor to dilate bronchioles parasym: visceral motor (vagus) to constrict bronchioles |
|
|
lympatic drainage
|
superficial & deep into tracheobronchial lymph nodes around roots of lobar & main bronchi and along sides of trachea
this drains into brochomediastinal trunks |
