Gross Anatomy - Respiratory Passages, Lungs, Pleural Cavities

Front 1

bronchial arteries

Back 1

arteries: small, origin from descending thoracic aorta

Front 2

bronchial veins

Back 2

2 sets: true: drain back to systemic circulation

bronchopulmonary: anatamose to pulmonary circulation

Front 3

pulmonary trunk

Back 3

L and R pulmonary artery towards hilum

Front 4

pulmonary veins

Back 4

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

Front 5

lymph of lungs

Back 5

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

Front 6

pulmonary plexus of lung

Back 6

folow bronchial tree from root of lung

efferent, afferent, parasym AND symp

Front 7

parasymathetic innervation of lung

Back 7

vagus nerve

Front 8

vagus nerve in lung

Back 8

bronchoconstriction

increase in secretion of mucous glands

conduct sensation from epithelial lining of passages

conduct sensory information from stretch receptors

Front 9

sympathetic innervation of lung

Back 9

upper thoracic and lower cervical ganglia

mildly constrict pulmonary vessels to increase arterial pressure

Front 10

parts of parietal pleura

Back 10

cervical pleura

costal pleura

mediastinal pleura

diaphragmatic pleura

Front 11

pulmonary ligament

Back 11

where parietal and visceral pleurae are continuous with each other

Front 12

pleural cavity

Back 12

separate for 2 sides, no continuity

lung is SURROUNDED by it, not IN IT

Front 13

pleural pressure

Back 13

negative pressure, keeps lung expanded

Front 14

costomediastinal recess

Back 14

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

Front 15

neurovascular supply of visceral pleura

Back 15

autonomic vasomotor from underlying lung

vascular supply from bronchial circulation

lyph drainage into lymph vessels underneath to its lung

Front 16

neurovascular supply of parietal plera

Back 16

sensory: same as adjacent structure (intercostal in costa pleura...phrenic in diaphragmatic pleura...)

vascular: same as vascular

rich lymphatic network along with stroma

Front 17

do lungs have the inherent ability to actively expand and contract?

Back 17

no!

Front 18

lung connections

Back 18

anatomical connection to visceral pleura, which is mechanically connected to parietal pleurae, which is anatomically connected to thoracic wall and upper diaphragm surface

Front 19

thoracic wall and breathing

Back 19

parietal pleurae move anteriorly superiorly and laterally as the ribs increase AP and transverse dimensions of the thoracic cavity
