What Happens to the Human Body After Death
Immediately after death, the human body undergoes a series of biological changes. When the heart stops beating, oxygen is no longer delivered to tissues, and the immune system ceases to function. Without immune defenses, microorganisms that were previously kept in balance during life begin to multiply.

These microorganisms include bacteria that naturally live in the mouth, nose, intestines, and on the skin. While these bacteria are typically harmless or even beneficial when a person is alive, after death they can grow uncontrollably and contribute to the process of decomposition.
