inflammatory extravascular fluid that has a high protein content, cellular debris and a high specific gravity; indicates significant alteration in normal permeability of small blood vessels (e g active inflammation); pus is a type of exudate which is rich in neutrophils and cell debris
the fluid plasma which leaks out of blood vessels due to an increase in capillary permeability The increased permeability, is caused by histamine, and bradykinin, which are released in response to tissue damage The formation of an exudate is the first step in the process of inflammation
Non-cellular, natural raw material that is secreted by plants, either spontaneously or after wounding Examples - Balsam Peru, Balsam Copaiba, etc
a fluid that has moved out of the capillary due to injury In the eye, a chronic inflammatory condition with small yellowish areas around the disc
Fluid cells or cellular debris which seeps from blood vessels into a body cavity or the tissues, often as a result of disease
Serous - clear fluid which leaks out through cell membranes and blood vessels, straw coloured Haemoserous - blood-stained fluid when serous fluid mixes with blood, ren/pink in colour Purulent - frank pus coming from the wound indicating infection, yellow/green in colour, may be brown/red if infection is causing wound to bleed
