Notation in mathematical model	Y_VRHL0
Allometric exponent	3/4

The parameter describes the dependence of blood flow through mitral valve from the difference between pressure in pulmonary vein and left atrium and left ventricular pressure. Its physical meaning – a value inverse to resistance of the blood flow in the specified part of vascular system. The parameter is included in mathematical description of a law of blood flow through vessels as a factor Y_VRHL in equations describing the blood flow through mitral valve:

(42)

where P_VR - pressure in pulmonary vein and left atrium, P_HL - left ventricular pressure.

The parameter is used for modelling of pathologic mode “mitral stenosis”. The main characteristic is a reduction of conductivity parameter in comparison with its normal value. The regurgitation factor in mitral valve r_VRHL is used for modelling of pathologic mode "mitral valve failure ".
