noun, plural: exudates

A fluid containing solutes, proteins, cells, or cellular debris discharged into nearby tissues or on tissue surfaces


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.

Plant exudates include viscous materials seeping from interstices or pores. Examples of exudates include saps, gums, resins, and latex.

Word origin: Latin exsūdāre [ex- (out) + sūdāre (to sweat)]
