WebQuestion. The alveoli and blood capillaries make up the gas exchange surface of the lungs, and as the arrows in the diagram (Figure 3) illustrate, this is where oxygen and carbon dioxide move in a particular direction. a) With reference to simple diffusion, explain why oxygen and carbon dioxide move in the directions illustrated by the arrows. WebLet's say, only half of their alveoli are working. That means that half of their surface areas is gone. So they're really not getting as effective gas exchange, because half their surface … how to revoke a grant of probate

WebHow does the structure of alveoli maximize gas exchange? The sac-like structure of the alveoli increases their surface area. In addition, the alveoli are made of thin-walled parenchymal cells. These features allow gases to easily diffuse across the cells. 3. What Animals use direct diffusion for respiration? flatworm, sea anemones, sponges 4. WebAir then travels down the pharynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles, which house the first site of gas exchange. The respiratory bronchioles open into the alveolar ducts, alveolar sacs, and alveoli.
