What happen to blood only just after departure?Does it clot right away ?

People say in 15 minutes if brain is OK, man can revive from death?
Answers:    Once your blood stops man circulated by your heart, it begins to separate into its different components. The blood cells settle in your lower areas, and the plasma rises to your upper areas. Because of this, departed people get "livor mortis," which is a darkening of the skin on lower areas of the body.
ar as I know, blood doesn't if truth be told "clot" when you die.

For the first few minutes after your heart stops, the brain can still survive on the oxygen in the blood around it; however, once this is used up, the brain cells begin to suffocate. Nerve cell can't grow back, so once your brain cells die, you're gone. Source(s): Forensic science class and general biology.
