What does the diffusion do in the alveoli? Diffusion in the alveoli is efficient because of some adaptations of the structure. 1. WebSome molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core. In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.

Web• moist enough to allow the cells to live • large enough to permit sufficient gas exchange • thin enough to permit rapid diffusion In respiration • blood entering the respiratory organ must be high in CO2and low in O2 • both gases must move into and out of the body tissues through diffusion WebThe respiratory surface must be kept moist in order for the gases to dissolve and diffuse across cell membranes. Organisms that live in water also need a way to obtain oxygen. Oxygen dissolves in water, but at a lower concentration in comparison to the atmosphere, which has roughly 21 percent oxygen.

WebWhen the frog is out of the water, mucus glands in the skin keep the frog moist, which helps them absorb dissolved oxygen from the air. They also use their buccal cavity lining which is rich in blood capillaries and always remains moist with mucus covering. This type of respiration is called buccal respiration.
