gas phase, although depending on the levels, it could be plasma.
It all depends on the size of the Laan, if the Laan is fastest it means its long its fastest short then shortest laans cannot diffuse properly, Laan expert here.

Exchange surfaces with rapid diffusion rates have several properties. These surfaces would have a high gradient on one side and active channels for diffusion.
Diffusion is more rapid in less dense medias. Molecules have more open space that way and can move faster and more freely.
The acts as a catalyst to speed up the diffusion process, allowing the molecules to overcome it; the activation energy causes the reaction to proceed at the faster rate.
Features of gas exchange surfacesHave a large surface area relative to the volume of the organism.They are thin, so have a short diffusion pathway.They have a moist surface where gases can dissolve first before they diffuse in our out.They are able to maintain the diffusion gradient down which the gases can diffuse.
Neither! Protists are mainly simple organisms made of a single cell. They are small enough to obtain their oxygen and remove wastes by diffusion. Diffusion is also rapid enough to distribute substances inside the cell. Therefore a circulatory system is not needed.

It allows for rapid diffusion of gasses.
Diffusion is more rapid in less dense medias. Molecules have more open space that way and can move faster and more freely.
Acculturation
Diffusion is a rapid process and is therefore limited to shorter distances. Transport is includes the change of wastes, nutrients and gases.
The alveoli have very thin walls, which allow for rapid diffusion into the surrounding capillaries. There are also many alevoli in the lung, and that increases the surface area dramatically, allowing for more diffusion to occur
Disadvantages of rapid growth in southeastern states
The acts as a catalyst to speed up the diffusion process, allowing the molecules to overcome it; the activation energy causes the reaction to proceed at the faster rate.
(a) Compare interstitial and vacancy atomic mechanisms for diffusion. (b) Cite two reasons why interstitial diffusion is normally more rapid than vacancy diffusion. Solution (a) With vacancy diffusion, atomic motion is from one lattice site to an adjacent vacancy. Self-diffusion and the diffusion of substitutional impurities proceed via this mechanism. On the other hand, atomic motion is from interstitial site to adjacent interstitial site for the interstitial diffusion mechanism. (b) Interstitial diffusion is normally more rapid than vacancy diffusion because: (1) interstitial atoms, being smaller, are more mobile; and (2) the probability of an empty adjacent interstitial site is greater than for a vacancy adjacent to a host (or substitutional impurity) atom.
