Osmoregulation

The regulation of water potential in an organism. Over many years, different species have developed evolutionary [[adaptations in relation to their environment due to the fact that any organism will always 'want' to have an ideal water concentration in its cells.Essentially, osmoregulation works around the natural forces of concentration gradients and water potential. The body will initiate a variety of countermeasures that re-navigate the flow of water around our body and either promote water retention or promote the secretion of water, depending on what environment the organism in question is situated in. See the [[animal and [[plant water regulation tutorial pages for related information in regards to evolutionary adaptations regarding osmoregulation.

Contractile Vacuoles?

You can't say "why." That presumes a "reason" exists. But consider what contractile vacuoles do - they effect osmoregulation in siolated cells such as those of paramecia. With very very few exceptions, human cels are organized - not isolated. Osmoregulation is matained ...

Re: Contractile Vacuoles?

As in the osmoregulatory contractile vacuoles in paramecia? Human cells don't need individual means for osmoregulation as oiur cells are not free living,
