Which of the following statements is FALSE Alveoli walls is one cell thick which increase the rate of diffusion of gases. Alveoli is well supplied with blood capillaries. Numerous alveoli help increase surface area to volume ratio facilitates exchange of gases. A thin film of moisture covering the surface of the alveolus allows membranes to slide over each other easily during breathing. None 25. What part(s) of the Respiratory System takes air to the lungs?
