Gaseous Exchange in Lungs ● At alveoli level, gaseous exchange occur through respiratory membrane (diffusion membrane) which is 0.2 mm thick (total thickness is much less than a mm). ● 𝗜𝘁 𝗰𝗼𝗻𝘀𝗶𝘀𝘁 𝗼𝗳 𝘁𝗵𝗿𝗲𝗲 𝗹𝗮𝘆𝗲𝗿𝘀: (i) Alveolar epithelium (thin squamous epithelium) (ii) Basement substance in between them (composed of a thin basement membrane supporting the squamous epithelium and the basement membrane surrounding the single layer endothelial cells of capillaries) (iii) Endothelium of alveolar blood capillaries ● Exchange of gases also occur between blood and tissues. ● O2 and CO2 are exchanged in these sites by simple diffusion mainly based on pressure/concentration gradient ● Pressure contributed by an individual gas in a mixture of gases is called partial pressure and is represented as pO2 for oxygen and pCO2 for carbon dioxide.
