EL6:
The rate of change of the total quantity of potassium in all of the body fluids (KTOTD)
is equal to the rate of intake of potassium (KID) minus the rate of excretion of
potassium in the urine (KOD).
EL7:
The total quantity of potassium in all the body fluids at any given time (KTOT)
is calculated by integrating with respect to time the rate of change of the potassium
in all of the body fluids (KTOTD).
EL7A:
Calculation of the freely mobile potassium in the body (approximately 616) by
subtracting the relatively fixed potassium in all the cells of the body
(approximately 3000) from the total potassium of the body (KTOT).
EL7B:
Calculation of the total potassium in the extracellular fluid of the body (KE) by
dividing the total freely mobile calcium from Block EL7A by a constant factor of
9.3333 (which is a distribution relationship of the freely mobile potassium between
the intracellular and extracellular fluid), and divided by a factor from Block EL11
that determines the activity of aldosterone on the distribution relationship of
potassium across the cell membranes.
EL8:
The concentration of potassium in the extracellular fluid (CKE) is equal to the
quantity of potassium in the extracellular fluid (KE) divided by the volume of
extracellular fluid (VEC).
EL19:
The extracellular fluid volume (VEC) is equal to the total volume of water in the
body (VTW) minus the total volume of water inside all of the cells of the body (VIC).
This is the CellML 1.1 "parent" file to test the Electrolytes Model.

by dividing the total potassium inside all the cells (KI) by the volume of fluid
inside all the cells (VIC).
Encapsulation grouping component containing all the components in the Electrolytes Model. The inputs and
outputs of the Electrolytes Model must be passed by this component.

EL1, EL2, and EL3:
The rate of intake of sodium (NAINT) is equal to the normal rate of sodium intake (NID)
times a salt appetite multiplier factor (STH). The rate of change of sodium in the
extracellular fluid (NED) is equal to the rate of intake of sodium (NAINT), minus the
rate of excretion of sodium in the urine (NOD), plus sodium entering the body in
transfused plasma (TRPL).
