WebDescribe the differences in transit time in reaching equilibrium with the alveolar compartment for NO2, CO, O2. NO2--very low transit time required to reach equilibrium (diffuse across membrane) CO--never reaches equilibrium, very low rise in partial pressure in the liquid in which it dissolves. WebDiffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs. WebSep 20, 2024 · Diffusion occurs when molecules move from an area of high concentration (of that molecule) to an area of low concentration. This occurs during the gaseous exchange as the blood in the capillaries surrounding the alveoli has a lower concentration of oxygen than the air in the alveoli which has just been inhaled. grace reformed church of flatbush
