日常生活中，人们都熟悉中口腔与胃，也比较重视它们的保健，却有意无意地疏忽了两者之间的连接部分——食管。从医学上看，这是一个长管状肌性器官，虽然没有显赫的“地位”与“身份”，但发挥着承上启下的作用，其生理使命是将在口腔里初步消化的食物与水输送到胃中。有人测算，人的一生中至少有20多吨食物与饮料，通过这段约40厘米长的“运输线”进入胃中，为全身提供热量与养分。如果换用汽车装载，可足足装满3辆解入牌大卡车，乃是人体生命的惟一“补给线”。
In daily life, people are familiar with the oral cavity and stomach, but also pay more attention to their health, but consciously or unconsciously neglected the connection between the two parts - the esophagus. Medically, this is a long tubular muscle organ that, although it does not have a prominent “status” or “identity,” plays a supporting role. Its physiological mission is to deliver food and water, initially digested in the mouth, to the stomach . It has been estimated that there are at least 20 tons of food and drink in a person’s life, entering the stomach through this approximately 40-centimeter “transport line”, providing calories and nutrients to the whole body. If you switch to the car loading, can be fully loaded with 3 unlocked truck, but the only “supply line” of human life.
