<prompt> All of the following are included in the pathogenesis of oedema except?Decreased hydrostatic pressure of capillariesDecreased plasma osmotic pressure of capillarieslymphatic obstructionIncreased vascular permeability  <response>: Pathogenesis of edema1 The increased hydrostatic pressure of capillaries2 Decreased plasma osmotic pressure of capillaries: It causes decrease in inward driving force. It results from Hypoproteinemia. When total plasma protein is below 5 gmdlA 113 normal 6-8 gmdl or albumin is below 2-5 gmdl normal 3.5-5 gmdl edema takes place.3 Defective removal of interstitial fluid by lymphatics: It is due to lymphatic obstruction.4 Increased vascular permeability5 Sodium salt and water retention
