WebThe efficiency of gas exchange in various areas of the lung is evaluated based on the concept of ventilation/perfusion (V/Q) relationship (Kremeier et al., 2024; Pizano et al., 2024). The process by which the air flows into and out of the alveoli is known as ventilation, whereas perfusion implies the flow of blood in pulmonary capillary. WebThe quantitative relation between stomatal aperture and gas exchange through the stomatal pore can be described by physical models derived from Fick's first law of diffusion. Such models, usually based on a simplified pore geometry, are used to calculate leaf conductance from stomatal pore dimensions or vice versa.

WebFick's Law essentially states that the rate of diffusion of a gas across a permeable membrane is determined by the chemical nature of the membrane itself, the surface area of the membrane, the partial pressure gradient of the gas across the membrane, and the thickness of the membrane. Fick's Law V'gas = D * A * ΔP/T 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 with the external environment, and occurs in the alveoli of the lungs.
