Death by natural causes

[brandonhawkins]

How does a coroner, doctor, or anyone for that matter, determine that someone died of natural causes? Is it just the fact that there are no markings, or other abnormalities, and everything just shut down? I am just confused by this.

If it means that your organs just start shutting down (obvious)... what order do they go in? What if your lungs stopped working before your heart...wouldn't an autopsy report look like you had been suffocated?

Or is there always a REASON (i.e. heartattack, stroke, etc.) but everyone is just told "natural causes" to lighten the impact?

Someone wanna explain this to me?
