Abstract:
In this paper, we follow the thermodynamic theory with internal variables of Kluitenberg evaluating the entropy production of red blood cell in saline solution and whole blood, respectively, when they are subjected to an ultrasound wave. From a thermodynamic point of view, blood is an open system; so to fully represent the entropy variation as function of frequency perturbation we employ phenomenological coefficients which allow us to qualitatively discriminate among classes of phenomena which cannot be observed in any other way. Therefore, a correlation between these coefficients and quantities experimentally measurable allows to a deeper knowledge of biological phenomena.

Entropy
When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...

Entropy and the Second Law of Thermodynamics
The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...
Enthalpy within the Cell

Enthalpy is also a state function. Enthalpy values for specific substances cannot be measured directly; only enthalpy changes for chemical or physical processes can be determined. For processes that take place at constant pressure (a common condition for many...
