bronchial arteries
|
arteries: small, origin from descending thoracic aorta
|
|
bronchial veins
|
2 sets: true: drain back to systemic circulation
bronchopulmonary: anatamose to pulmonary circulation |
|
pulmonary trunk
|
L and R pulmonary artery towards hilum
|
|
pulmonary veins
|
single vein from each lobe. middle lobe in right joins veins from upper lobe
each lung sends two veins to left atrium: R and L superior + inferior pulmonary veins |
|
lymph of lungs
|
pulmonary LN; within lung
bronchopulmonary: LN in hilum tracheobronchial: around bifurcation of trachea paratracheal: either side of tracea L and R bronchomediastinal trunks: unite with other large LNs in the root of the neck |
|
pulmonary plexus of lung
|
folow bronchial tree from root of lung
efferent, afferent, parasym AND symp |
|
parasymathetic innervation of lung
|
vagus nerve
|
|
vagus nerve in lung
|
bronchoconstriction
increase in secretion of mucous glands conduct sensation from epithelial lining of passages conduct sensory information from stretch receptors |
|
sympathetic innervation of lung
|
upper thoracic and lower cervical ganglia
mildly constrict pulmonary vessels to increase arterial pressure |
|
parts of parietal pleura
|
cervical pleura
costal pleura mediastinal pleura diaphragmatic pleura |
|
pulmonary ligament
|
where parietal and visceral pleurae are continuous with each other
|
|
pleural cavity
|
separate for 2 sides, no continuity
lung is SURROUNDED by it, not IN IT |
|
pleural pressure
|
negative pressure, keeps lung expanded
|
|
costomediastinal recess
|
part of sternal pleural reflection. the reflection begins at sternal angle at midline, descends vertically behind sternum, and deviates laterally at end
left sternal pleural reflection begins more superiorly, around 4th costal cartilage, due to the cardiac notch |
|
neurovascular supply of visceral pleura
|
autonomic vasomotor from underlying lung
vascular supply from bronchial circulation lyph drainage into lymph vessels underneath to its lung |
|
neurovascular supply of parietal plera
|
sensory: same as adjacent structure (intercostal in costa pleura...phrenic in diaphragmatic pleura...)
vascular: same as vascular rich lymphatic network along with stroma |
|
do lungs have the inherent ability to actively expand and contract?
|
no!
|
|
lung connections
|
anatomical connection to visceral pleura, which is mechanically connected to parietal pleurae, which is anatomically connected to thoracic wall and upper diaphragm surface
|
|
thoracic wall and breathing
|
parietal pleurae move anteriorly superiorly and laterally as the ribs increase AP and transverse dimensions of the thoracic cavity
