WebAdaptation of alveoli: The alveoli present in the lungs have thin walls composed only of a single layer of cells in order to minimize the diffusion distance. Their walls are moist which helps the gases to diffuse better. They are richly supplied with blood capillaries to ensure the efficient exchange of gases with the bloodstream. WebAlveoli have features that speed up the rate of diffusion so that gases can be exchanged quicly. They have a thin exchange surface - the alevolar epithelium is only one cell thick, which means there's a short diffusion pathway, which speeds up diffusion. crypto to make you a millionaireWebThe humidified air enters the alveoli, where gas exchange occurs. In alveolar air, the values for PO2 and PCO2 are changed substantially when compared with inspired air.
