Yes, a body can still exhibit signs of bleeding after death, though it's not active bleeding in the same way as it is in life. This is primarily due to postmortem processes.
Postmortem Bleeding: A Clarification
It's crucial to understand that bleeding after death is not a result of a living circulatory system. Instead, it is largely a passive process caused by gravity and the remaining blood pressure in the body. Specifically, postmortem lividity (livor mortis), as described in the reference material, is the settling of blood in the lowest parts of the body due to gravity. This begins immediately after death because the heart stops actively pumping blood. The blood pools, causing discoloration on the skin. While this isn't "active" bleeding like a cut or wound actively producing blood flow, it can appear as such.
- Example: If a deceased person is lying on their back, blood will pool in the back, causing purplish discoloration. If their position changes after death, new patterns of discoloration will appear.
This passive blood pooling can be misinterpreted as bleeding. Any pre-existing wounds might also show residual blood drainage due to gravity, adding to the visual appearance of post-mortem bleeding. However, it's important to emphasize that the circulatory system is no longer functioning, and therefore, no new blood is being generated or actively expelled.
