In fact, I think as long as people cherish life, I think any organ should be protected, because it is a part of us and nothing is indispensable. Of course, if we have to distinguish an important level, I think the heart, head and stomach need protection.

Let's talk about the heart first. As we all know, to judge whether a person is still alive, we can listen to whether his heart is still beating, whether his breath is still breathing and so on. So I think the heart should be well protected. If the heart stops beating, it means that it is not far from death, or even dead. However, as far as the heart is concerned, we should take good care of it except for some helpless diseases, right?

Then our head. The head can be said to be a person's soul, and we all think with our brains. If the head is gone, it can be said that a person no longer exists. Just like the punishment of beheading in ancient times, people can't live if they behead. So in life, we should take good care of our heads and avoid head injuries caused by collisions, especially those naughty children.

Then there is the stomach. Although the stomach is only a part of our digestive system, we should actually protect it. Our nutrient digestion depends on it. In addition, modern people usually don't eat on time, so modern people generally have a bad stomach. Therefore, from a modern point of view, we should take good care of our stomach, because this problem is almost universal among modern people.

Of course, as a part of our body, we should take care of all organs, not just one at a time. We should protect all organs. Because every organ has its function, we can't lose it.
