Commentary to the Fig.26:
1: Normal situation, filtration equilibrium is attained at
the border of 1st and 2nd third of the capillary length
2. Lowered hydraulic conductance (nephritic diseases),
filtration equilibrium is not attained, GFR declines
3. Contraction of vas afferens (e.g., strenuous exercise) ?
4. Postglomerular resistence enhanced ? ?(Ra + R e) ? ?GFR
5. Plasma proteins ? (multiple myeloma, amyloidosis, hemolysis)
6. Glomerulonephritis: ?(Ra + R e) ? ?RPF. Decline of
conductivity hampers attaining of filtration equilibrium ? ?GFR
