Diagrams of Lungs Pleura – layer 3 The two layers of pleura (orange) are held together by a thin layer of pleural fluid (yellow) by cohesive and adhesive forces. The visceral pleura is connected to the lung while the parietal pleura is attached to the chest wall. The pleura and fluid as a unit bind the chest wall to the lungs. The cohesion and adhesion that results keeps the outer chest cage of bone and muscle in intimate contact with the lungs, being pulled and pushed together in the harmonious dance of respiratory movement.Ashley Davidoff, M.D. TheCommonVein.net 42540b06 THE LUNGS AND THE TRACHEOBRONCHIAL TREE CT Rendering of Lungs and Airways in Blue and RedAshley Davidoff MD TheCommonVein.net lungs-0701 CT Rendering of Lungs and Airways in BrownAshley Davidoff MD TheCommonVein.net lungs-0702 CT Rendering of the Pulmonary Parenchyma in BlueAshley Davidoff MD TheCommonVein.net lungs-0011 LUNGS INSIDE THE CHEST CAVITYby Ashley Davidoff MD TheCommonVein.net lungs-0016 Tracheobronchial Tree42474b18.800 lung trachea bronchi tracheobronchial tree Ashley Davidoff MDTheCommonVein.net 42474b18.800 Gingko ChestTracheobronchial Tree Tree, flower, tracheobronchial tree, trachea bronchi lungAshley Davidoff TheCommonVein.net 32620b14.800b02p Parts of the lungs82738p chest lung connective tissue pulmonary artery pulmonary vein axial interstitial tissue secondary lobule lobes segments trachea bronchi interlobular septa polygonal Ashley Davidoff MDTheCommonVein.net A coronally reformated 3D image revealing the bronchial anatomy, from the trachea, (about) 1.6cms mainstem bronchi to the medium sized airways and finally to the small airways (2mm and less).TheCommonVein.net 32679 Gingko ChestTracheobronchial TreeTree, flower, tracheobronchial tree, trachea bronchi lungAshley Davidoff TheCommonVein.net lungs-0010 Respiratory Motion of the Lungs3 D rendering looking down the trachea with the lungs on either side showing the waves of respiratory motion and its effect on the surrounding air.
