Physical Changes
Within a few minutes of death, the body begins to undergo physical changes. As the heart stops beating, the body's cells no longer receive oxygen, and the body begins to cool. Rigor mortis, the stiffening of muscles, begins within two to four hours of death and can last for several days. The body also begins to lose its natural color, becoming pale or bluish-gray.
Decomposition
The body will begin to decompose soon after death. Bacteria in the body will start breaking down cells, releasing gases and fluids that can cause the body to bloat. The body will become bloated and discolored, and the smell of decomposition will become more and more pungent. Depending on the environment, the body will decompose at different rates, but typically it takes between two and eight weeks for the body to fully decompose.
Final Resting Place
The final resting place of the body depends on the wishes of the deceased, and their family. Many people choose to be buried in a cemetery, while others opt for cremation. In some cultures, the body of the deceased may be placed in a tomb or mausoleum, while in others, the body may be buried in a crypt or cave.
