All of the following are included in the pathogenesis of oedema except?
Correct Answer: Decreased hydrostatic pressure of capillaries
Description: Pathogenesis of edema
1) The increased hydrostatic pressure of capillaries
2) Decreased plasma osmotic pressure of capillaries: It causes decrease in inward driving force. It results from Hypoproteinemia. When total plasma protein is below 5 gm/dl(A 113) (normal 6-8 gm/dl) or albumin is below 2-5 gm/dl (normal 3.5-5 gm/dl) edema takes place.
3) Defective removal of interstitial fluid by lymphatics: It is due to lymphatic obstruction.
4) Increased vascular permeability
5) Sodium (salt) and water retention
