Heart ventricle.
like
QHP 2008 / VascularCompartments/LeftVentricle/*
The pressure-volume characteristics of both ventricles in diastole
and systole will be described using a power function.
P = A * (V ^ n)
P = Pressure
V = Volume
A = Scale Factor
n = curvature
The function is invertable.
V = (P/A) ^ (1/n)
