As an expert in the field of forensic science and biology, I can provide you with an understanding of the post-mortem changes that occur in the human body and how they relate to the viability of organs after death.

The concept of "organs living" after death is a bit of a misnomer because once the heart stops beating and blood circulation ceases, organs are no longer functioning in the way they do in a living body. However, the cells within organs can remain viable for varying periods of time depending on several factors, including the conditions after death, the type of organ, and the preservation methods used.

Here's a breakdown of what happens to organs post-mortem:


1. Heart: The heart stops beating, and without blood flow, the cells begin to die within minutes to hours.


2. Brain:脑细胞死亡相对较快，通常在氧气供应中断后几分钟内开始，但是某些细胞可能在几小时内仍然存活。


3. Lungs:肺部细胞也会在血液循环停止后很快开始死亡，但是通过机械通气和适当的处理，它们可以在体外保持功能状态数小时。


4. Liver:肝脏是器官捐赠中一个重要的器官，它可以在体外存活一段时间，大约几小时，尤其是在低温保存条件下。


5. Kidneys:肾脏同样可以在适当的条件下在体外存活数小时，这也是器官捐赠中常见的器官。

It's important to note that while cells within organs may remain viable for some time after death, the organs as a whole are not "alive" in the traditional sense. The term "viable" in this context refers to the potential for cells to be used for transplantation or other medical purposes.
