Gas exchange diffusion
WebThe diffusion coefficient of gases is important when comparing different gases in the lung. Let's take CO2 and O2. They are similar in molecular weight, but CO2 is about 20x more soluble than O2 in plasma, and therefore diffuses faster! This shows how the diffusion coefficient is important.

WebDiffusion Defect Overview Diffusion Defects refer to deficiencies in oxygen pulmonary gas exchange that yield abnormally low partial pressures of arterial oxygen. As described in oxygen pulmonary gas exchange, diffusion of oxygen from the alveolar space to the pulmonary capillaries in a healthy lung is normally perfusion-limited. WebGas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up. External respiration is the exchange of gases …

WebJun 8, 2024 · Gas Exchange across the Alveoli In the human body, oxygen is used by cells of the body’s tissues to produce ATP, while carbon dioxide is produced as a waste product. The ratio of carbon dioxide production to oxygen consumption is referred to as the respiratory quotient (RQ), which typically varies between 0.7 and 1.0.
