Aquaporins - Novel approaches to old problems
As all life on this planet evolves around water, it is important for our bodies to be able to regulate it. This may be done passively, but just like with water in the ocean, if we were to rely solely on passive transport (such as evaporation), the flow of water would be too slow for biological functions to uphold the homeostasis that is so important for us to survive. All organisms have thus devel
