Alveoli are adapted for gas exchange with very thin walls, a large surface area, and a good blood supply to maximize diffusion rates and maintain concentration gradients.
Como os alvéolos são adaptados para a troca gasosa? Paredes muito finas - minimiza a distância de difusão. Enorme área de superfície para maximizar a taxa de difusão. Bom suprimento de sangue para manter o gradiente de concentração.
