Cyclone â found in the luxury Neorest toilets, the Cyclone flushing system is just like the Double Cyclone system, only it uses one powerful nozzle of water instead of two due to the Neorest not having a tall tank. The Cyclone is a quiet flush and does not make a refilling noise after the flush.
Confidence votes 35. The Diffusion is the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the blood. So blood that is pumping through the capillaries in the lungs has a low concentration of O2 and a high concentration of CO2, in the alveoli it is high concentration O2 low concentration CO2.
the alveoli are the primary gas exchange units of the lung quite simply they are the point where the gas blood barrier is thin enough to permit rapid gas exchange to get into the blood oxygen is diffused through the alveolar epithelium a thin interstitial space and the capillary endotheliumhe alveoli are the primary gas exchange units of the lung quite simply they are the point where the gas blood barrier is thin enough to permit rapid gas exchange to get into the blood oxygen is diffused through the alveolar epithelium a thin interstitial space and the capillary endothelium
