Pleura, Lungs, and Lung Development Flashcards
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?
Pleural cavity
Serous fluid
How are two layers of pleura held together?
Surface tension
Regions of parietal pleura
Cervical Costal Diaphragmatic Mediastinal I
What are regions of parietal pleura in contact with?
Endothoracic fascia
Innervation of parietal pleura and what is it sensitive to?
Phrenic and intercostal
Localized pain
Is visceral pleura sensitive to localized pain and what is innervation?
No
Visceral affarent nerves
Suprapleural membrane covers which part of parietal pleura?
Cervical
Costodiaphragmatic recess
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
Costodiaphragmatic recess
Pneumothorax and what is can cause
Air in the lung
Collapsed lung
Tension pneumothorax causes
Shifting of the mediastinum which can compress a lung
Lobes of the right lung and fissures separating
Superior Middle Inferior Horizontal separates sup and mid Oblique separates mid and inf
Lobes of the left lung and fissure
Superior and inferior
Oblique separates
2 structures found in superor lobe of left lung
Cardiac notch and lingula
Bronchopulmonary segments
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
Apical
Posterior
Anterior
BP segments of right middle lobe
Lateral
Medial
BP segments of right inferior lobe
Superior Medial basal Anterior B Lateral B Posterior B
