WebIf the alveoli in our lungs fill with fluid (pulmonary edema), the distance the gases must travel increases, and their transport decreases. Facilitated diffusion is diffusion that is helped along (facilitated by) a membrane transport channel. 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.

WebAlveoli have a large surface area. This allows more space for oxygen molecules to move across from the alveoli to the blood. They have moist surfaces. Gases dissolve and form a solution then... WebWhen water passes over the gills, the dissolved oxygen in water rapidly diffuses across the gills into the bloodstream. The circulatory system can then carry the oxygenated blood to the other parts of the body.
