Is the appendix really surplus
The function of the appendix seems and perches the bacterium enormous in quantity is correlated with in the human digestive tract. In the human body, the quantity of the bacterium should far exceed the cells of the human body, among them most bacteria are beneficial to people, and help us to digest the food. However, the bacterium in the intestine dies or is removed sometimes. Some diseases, will remove the beneficial bacterium in the intestine such as cholera, amoebic dysentery. In this case, appendix can exhibit one's skill. Its only picture " Back up the plate " ,Can restart the intestinal system deleted when ill.
But the appendix does not rigorously enforce the bacterium processing factory in the meaning, because it fosters the way of the bacterium a bit special. For example, if cause a group of death of fungus in the intestine because of illness or others alone, the appendix will utilize the bacterium that collect from other people to foster these bacteria again easily. Certainly, others' bacterium is through the way of all sorts of contact food that the appendix is gathered, for example have a dinner party or share tableware,etc., wash hand, have meal, collect, arrive a own one to be under one's command other bacterium of people, preserve. But in front of contemporary intensive population or when disease prevail, if cholera influences a certain area, the appendix can not cultivate bacteria easily. Even so, appendix afford to send in when even.
The appendix has negative function such as inflammation too. But in developing countries, the morbidity of appendicitis should be lower than the developed country. This means in the area with better sanitary condition, appendicitis may be that the bacterium touches off the body immune system and produces the result of the overreaction. Because here in the not area of the hygiene, people contact more bacteria, the human immune system includes the appendix, will suit to a lot of bacteria, will not regard them as the outside enemy to treat, therefore does not produce immunoreaction. In the area with better sanitary condition, there are less bacteria that people contacted, it is not harmful to human body that there are more bacteria (these bacteria slightly) ,Will cause the response of the internal immune system, bring out inflammation, including appendicitis.
In case of appendix inflammation, if does not excise in time, may cause people desperately. Appendicitis can take place in age any, but with between twenty and fifty for see for have illness coming on peak 20 to 30 years old more. Up till now, acute appendicitis has stilled have 0.1% - 0.5% mortality; Once filling the air peritonitis happenedding, its mortality can be up to 5%-10%.
