gas exchange is a process of physics, where the gases are distributed between two (sometimes through a permeable membrane, sometimes through separate openings or pores) compartments in space again. Gas exchange is part of the breathing as the transport of respiratory gases between the surrounding external medium (air, water) and the verstoffwechselnden target cells instead. The gas exchange can be supported by active muscle work. In air conditioning gas exchange is achieved primarily by fans, but the heat can be used as appropriate for gas exchange.
of gas exchange is spoken, if it is acting gases, which are physically dissolved in liquids (for example, absorption of oxygen from water through gills into the blood).
In the case of multi-cellular differentiated organisms often specialized institutions as part of the external respiration for gas exchange and its active support responsible. As external respiration while all the parts of the body are referred to, which for gas exchange and transport of charge between the ambient medium and target cells.
factors that influence the gas exchange
The exchange of a boundary layer (in biology: membrane) requires for these substances as unrestricted permeability (permeability , usually a semi-permeability). It is also essential to encourage the exchange to have the largest possible surface membrane.
