How is agonal coagulation most accurately described?

Agonal coagulation refers to the physiological process that occurs at the end of life, particularly in the moments before death. It is characterized by the transformation of blood into a thickened mass. This condition typically arises due to the cessation of circulation and the resulting changes in blood viscosity. When the heart stops pumping effectively, blood flow slows down, allowing for the clotting process to initiate.

In normal circumstances, blood remains in a fluid state due to the presence of anticoagulants that are naturally found in plasma. However, during the agonal phase, these anticoagulants may become less effective, causing the blood to clot and form a thicker mass as it pools and settles in various parts of the body.

Understanding this process is crucial in fields such as forensics and medicine, as it can provide insights into the timing of death and the biological changes that occur during the dying process.
