| transudate | <physiology> A transudate is a plasma derived fluid substance which has passed through a membrane or been extruded from a tissue, sometimes as a result of inflammation. The fluid accumulates in tissue and causes oedema and is the result of increased venous and capillary pressure, rather than altered vascular permeability (which leads to cellular exudate formation). Compare: exudate. (27 Jun 1999) |
