Pulmonology Flashcards
Superior and middle lobe is separated from the inferior lobe by the ___.
oblique
What separates the left superior and inferior lobes?
oblique fissure
what does the horizontal fissue do?
separates superior and middle lobe in the right lung
What four structures are part of the hilum?
- Pulmonary artery (superiorly located, large)
- Pulmonary vein (anteroinferiorly located, smaller and thinner than vein)
- Main bronchi (posteriorinferior thickest wall w/ cartilage)
- Pulmonary ligament
Grooves to know
left grooves to know
Which lung is the cardiac impression more pronounced on?
Left
Where is the cardiac notch and lingula located?
On the superior lobe of the left lung
where can lung cancer be derived from and what nerves could be involved?
Lung tissue or bronchi, it can also involve phrenic vagus and recurrent laryngeal nerves
Lobectomy and segmentectomy?
- Removal of lobe
- removal of segments within lobes
What is pleuritis?
- inflammation of pleura producing roughness on lungs making breathing difficult
How does pulmonary collapse occur?
- enough air enters pleural cavity to break surface tension btw two layers of pleura, and the elasticity of the lung causes them to collapse
Pneumothorax?
- entry of air into pleural cavity fromo penetrating would to thoracic wall or rupture of pulmonary lesion into pleural cavity resulting in collapse
Hydrothorax?
- Accumuluation of excess fluid in pleural cacity usually result of fluid escape into pleural cavity or pleural effusion
What is the sternal line?
Costal parietal pleura turns into the mediastinal pleura at this point
