water (hydrostatics) and nutrients are controled by the cell membrane, which utilizes energy to maintain the concentration differentials. Temperature control is only found in higher animals (mammals and birds) and is managed by brown fat which has unusually high concentrations of mitocondral in their cells. Mitocondria are concerned with the manufacture of ADP the chief energy storage compound of nearly all life.
The layer of ozone does maintain suitable conditions for life. It protects the humans from the UV interaction.
The conditions here on Earth, of course!
There is no known evidence of life on Venus. The planet is very hot and does not have the conditions necessary for life to thrive.
