有一个器官,仅有1.5英寸长,在人体中的地位最低,但最不怕脏,埋头苦干为你服务一辈子……,没错,笔者说的是肛门。它甘居于消化道的末端,肩负排污的生理重担,维持消化系统的正常运作。不像人体的有些器官那样成双成对,一人只有一个,一旦发生损害往往难以修复,所以平时的养护就显得更加重要了。 There is an organ, only 1.5 inches long, the lowest position in the human body, but the most afraid of dirty, hard work for your life ... ..., yes, I said the anus. It is willing to live in the end of the digestive tract, shoulder the physiological burden of sewage to maintain the normal operation of the digestive system. Unlike some organs of the human body, which are paired in pairs, there is only one person at a time. Once the damage occurs, it is often difficult to repair it, so the usual maintenance becomes even more important.
