Characteristic of exudative fluid is - 
Select and explain. 
A. Low protein content, B. Specific gravity < 1.012, C. Normal vascular permeability, D. Cellular debris
D: Cellular debris
Answer: D: Cellular debris 
Explanation: Ans. is 'd' i.e., Cellular debris Types of edema fluidIn edema, the fluid accumulated in interstitial fluid may be either a transudate or an exudate. Exudate is an inflammatory fluid that contains high protein content, cellular debris, and specific gravity >1.020. It occurs due to increased vascular permeability.Transudate contains low protein (mostly albumin) with specific gravity < 1.012.It is an ultrafiltrate of plasma that results from hydrostatic or osmotic imbalance between intravascular and extravascular compaments despite normal vascular permeability
