WebA membrane (or a barrier) with special structural features can be a permeability restriction to distribution of drugs to some tissues. Some of the important simple and specialized physiological barriers are: 1. Simple capillary endothelial barrier 2. Simple cell membrane barrier 3. Blood-brain barrier 4. Blood-CSF barrier 5. WebPermeability refers to how connected pore spaces are to one another. If the material has high permeability than pore spaces are connected to one another allowing water to flow from one to another, however, if there is low permeability then the pore spaces are isolated and water is trapped within them.
