Gas exchange allows oxygen to move … WebDescribe how the lungs are adapted for gas exchange (6 marks) -There are a large number of alveoli, increasing the surface area available for gas exchange. The alveoli have many infoldings, further increasing the surface area. - The walls of the alveoli are thin, they are one cell thick. This reduces the diffusion distance for gases, increasing ...
