What type of changes does Postmortem Physical Changes encompass?

Postmortem Physical Changes refers specifically to the observable alterations that occur in the body after death, which do not involve changes in chemical composition. These changes include rigor mortis (stiffening of muscles), livor mortis (settling of blood due to gravity), and algor mortis (cooling of the body), all of which are physical in nature.

Understanding that these changes are distinctly physical is crucial; they manifest as visible shifts in the body's condition but do not alter the chemical makeup of bodily tissues at the molecular level. This distinction reinforces the idea that while physical characteristics may change, the inherent chemical structure of the body remains unchanged during the initial phase of decomposition.

The other options refer to either chemical processes, emotional aspects, or growth, which do not align with the definition of postmortem changes focused on purely physical manifestations.
