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.
Alveoli are tiny sacs in the lungs that perform gas exchange. That is the main process of respiration where the body gets rid of carbon dioxide and picks up oxygen which is us â¦ ed in metabolism.  They have supply of oxygenated and de-oxygenated blood surrounding their surface giving them a high blood supply.he alveoli remove the carbon dioxide from the blood in the capillaries and exchange it with oxygen to be taken to o â¦ ther parts of the body. The carbon dioxide is taken out of the body when we exhale.
