This study uses a thermodynamic analysis to evaluate the minimum work requirements for urine production in the human kidney and provide a new perspective on the energy costs of urine production. In this study, black-box models are used to compare the Gibbs energy inflow and outflow of the overall kidney and physiologically-based subsections in the kidney, to calculate the work of separation for urine production %K Human kidney %K Urine production %K Separation work %K Gibbs energy %K Energy balance %K Sensitivity analysis %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5267413/
