noun, plural: exudates
Animal and human exudates pertain to any fluid oozing out from the blood vessels, especially as a result of inflammation. When infection is present, the discharged fluid may contain white blood cells. In instances wherein there is vascular damage, red blood cells may also escape and be found in the exudate.
Word origin: Latin exsūdāre [ex- (out) + sūdāre (to sweat)]
