What happens to the blood inside your body when you die?
gpt
A condition known as lividity occurs, in which all the blood will pool towards the lowest point of the body's resting place because of gravity, and then clot. If someone was to die while laying on their back, bruising would occur on posterior aspects of the body. This can actually show if a body has been moved after death. For example, if a body was found face up with bruising on the face and stomach, it would show that the person has died face down, but was flipped around.
