Imbibition (Latin imbibere - to absorb) - the third and last stage of the formation of cadaveric spots on dead flesh. It appears 48 hours after death . A characteristic feature for this stage is the special βresistanceβ of purple-purple spots. When pressed, they do not become paler and do not disappear. Used in forensic practice, as a term, with inaccurate determination of the time of death.

Process Flow
Imbibition is applied to cases of impregnation of body tissues with a liquid (for example, with blood when hemorrhages, hydrops fluid with edema). However, most often they speak of cadaveric imbibition - impregnation of corpse tissues with hemoglobin of blood. Cadaveric imbalance occurs 48 hours after death and consists in the fact that, when blood is decomposed, hemoglobin leaves the red blood cells and stains the blood plasma; subsequently, plasma with hemoglobin seeps through the walls of the vessels, soaking the surrounding soft tissue. The most sharply cadaveric imbibition is expressed in places of the greatest accumulation of blood , namely in the lower parts of the corpse [1] .
Types of Gambling
The term imbibition is used to denote the impregnation of one or another liquid medium of some more dense material. However, in the physical sense, the mechanism of this impregnation may be different:
- molecular imbibition (impregnation of molecular adsorption of a liquid with a dense material);
- capillary imbibition;
- colloid swelling as the basis of imbibition;
- imbibition with some artificial coloring matter;
- cadaveric imbibition (impregnation of hemoglobin with blood tissue) [2] .
Forensics
Cadaveric imbibition has important forensic significance , as it can help establish the time that has passed since the moment of death. In addition, acquaintance with changes in the corpse, depending on imbibition, is necessary for a forensic expert in view of the fact that such changes can sometimes simulate intravital hemorrhage from damage, and pneumonia in the lungs [2] .
