When the fluid in the cavity increases in pathological state, hydrops occurs, which is called serous cavity hydrops. According to the nature of effusion, it can be divided into leakage and exudation.
The exudate is easy to coagulate because it contains fibrinogen and thromboplastin released by tissue and cell destruction.
Extended data
A word "inflammatory exudation" is often mentioned. Exudation is caused by inflammatory exudation or tumor, chemical or physical stimulation, so there are relatively many protein and cells in it, so it can be understood as turbid water:
Protein content is high (1);
(2) There are many cell components;
(3) turbidity is easy to solidify;
(4) High density.
