Flashcards in Pleura, Lungs, and Lung Development Deck (69)
Layers of pleura and what they touch
Visceral - on the lungs
Parietal - on the surface
What is the space between the two layers of pleura and what does it contain?
How are two layers of pleura held together?
Regions of parietal pleura
What are regions of parietal pleura in contact with?
Innervation of parietal pleura and what is it sensitive to?
Phrenic and intercostal
Is visceral pleura sensitive to localized pain and what is innervation?
Visceral affarent nerves
Suprapleural membrane covers which part of parietal pleura?
Lowest point of pleural cavity
Recevies drainage of pleural cavity if standing up
Costomediastinal recess function
Allows lungs to expand into area during inhalation
Hemothorax and where it will drain
Blood in pleural cavity
Pneumothorax and what is can cause
Air in the lung
Tension pneumothorax causes
Shifting of the mediastinum which can compress a lung
Lobes of the right lung and fissures separating
Horizontal separates sup and mid
Oblique separates mid and inf
Lobes of the left lung and fissure
Superior and inferior
2 structures found in superor lobe of left lung
Cardiac notch and lingula
Anatomically separate respiratory units surround by connective tissue CONTINUOS with visceral pleura
What does each BP segment receive?
A segmental (tertiary) bronchus with accompnaying branch of a pulmonary artery (intrasegmental)
Branches of pulmonary veins located
In connective tissue between BP segments (intersegmental)
Pulmonary veins and pulmonary arteries carry
Arteries - deoxygenated blood
Veins - oxygenated
Sternal angle is at what levle and what is significance
T4...this is where trachea splits to left and right primary bronchus
Right vs. left primary bronchus
Right wider and more vertical than left...means objects more likely to go here
How many secondary bronchi from each primary branch?
3 on right
2 on left
Tertiary bronchi go to
individual BP segments
BP segments of right lung superior lobe
BP segments of right middle lobe
BP segments of right inferior lobe
BP segments of left superior lobe
Lingular division has 2 (superior lingular and inferior lingular)
BP segments of left inferior lobe
