Mechanical Forces Bringing Air to Alveoli Chest Wall, Diaphragm, Alveolar Expansion The five major layers that keep the air moving include the outer bony cage, the muscular layer represented in maroon, the pleural complex (orange yellow orange) the lung (blue) and surfactant within the alveolus.

Keeping the Lungs attached to the Chest Wall via A Two Layered Pleura ? Capillary Forces The coronally reformatted image of the lung parenchyma has been outlined with the visceral pleura, (pink) the pleural fluid in the pleural space, (orange) and the parietal pleura. (green) Note how at end expiration the parietal pleura in the costophrenic sulcus extends beyond the lung margin so that the visceral pleura is absent in the costophrenic sulcus and there are two layers of parietal pleura facing each other. During inspiration the lung expands into this space. 32634b10 Key Words lung pleura pulmonary Ashley Davidoff MD TheCommonVein.net

Elastic Forces This CTscan shows a theoretical changes of the aortic wall during diastole (a) sytolic expansion (b) and return to normal in diastole (c) In systole (b) the suprarenal artery is expanded by the pulse but is relatively decompressed by the the low resistance and high flow renal arteries. The infrarenal aorta is relatively more expanded in systole (b) since the iliac arteries offer a relative resistance. This increased resistance causes the elastic tissue in the aorta to stretch (b) so that the recoil in diastole (c) results in a sustained forward moving force assisting the blood to get to their most distal destination ? the feet. When the aorta starts to lose its elasticity the recoil of systole gradually is weakened so that the aorta does not return to its normal diameter after each systolic expansion. Over many years this lack of recoil is progressive so that the resulting wall is weaker and dilated, until an aneurysm can be formed. 24877c03 key words CVS artery aorta AAA infrarenal circulatory elasticity recoil Ashley Davidoff MD TheCommonVein.net
