<para>
This is a CellML 1.1 version of the Kidney Module of the Guyton Circulation model. To run, click on "Solve using OpenCell" and all
dependent files and components will be imported. To run offline, please download all files from the <ulink url="/workspace/guyton_kidney_2008/">workspace</ulink> into the same directory and open
"kidney_parent.cellml" in OpenCell.

<title>Model Status</title>
<para>
This CellML model has not been validated. The equations in this file may contain errors and the output from the model may not
conform to the results from the MODSIM program. Due to the differences between procedural code (in this case C-code) and
declarative languages (CellML), some aspects of the original model were not able to be encapsulated by the CellML model (such
as the damping of variables). Work is underway to fix these omissions and validate the CellML model. We also anticipate that
many of these problems will be fixed when the CellML 1.0 models are combined in a CellML 1.1 format.

<title>Model Structure</title>
<para>
Arthur Guyton (1919-2003) was an American physiologist who became famous for his 1950s experiments in which he studied the physiology
of cardiac output and its relationship with the peripheral circulation. The results of these experiments challenged the conventional
wisdom that it was the heart itself that controlled cardiac output. Instead Guyton demonstrated that it was the need of the body tissues
for oxygen which was the real regulator of cardiac output. The "Guyton Curves" describe the relationship between right atrial pressures
and cardiac output, and they form a foundation for understanding the physiology of circulation.
</para>
<para>
The Guyton model of fluid, electrolyte, and circulatory regulation is an extensive mathematical model of human circulatory physiology,
capable of simulating a variety of experimental conditions, and contains a number of linked subsystems relating to circulation and its
neuroendocrine control.
</para>
<para>
This is a CellML translation of the Guyton model of the regulation of the circulatory system. The complete model consists of separate
modules each of which characterise a separate physiological subsystems. The Circulation Dynamics is the primary system, to which other
modules/blocks are connected. The other modules characterise the dynamics of the kidney, electrolytes and cell water, thirst and
drinking, hormone regulation, autonomic regulation, cardiovascular system etc, and these feedback on the central circulation model.
The CellML code in these modules is based on the C code from the programme C-MODSIM created by Dr Jean-Pierre Montani.
</para>
<para>
This particular CellML model describes the function of the kidney. This section is a highly simplified analysis of renal function,
including analysis of blood flow through the kidney and of the formation of glomerular filtrate. Then the changes that occur in the
filtrate as it passes through the tubules are calculated. However, only four substances are considered as they pass through the
tubules: sodium, potassium, urea, and water. The control effects of angiotensin, aldosterone, antidiuretic hormone, and nervous
signals are also presented.
