现行九年制义务教材《生物》第二册第39页“淋巴循环”的提法笔者认为不妥，若能修改为“淋巴回流”则较为有利于教学，也更为科学、合理。循环一词单从其意义来解释，是指事物周而复始地运动或变化。例如，血液循环就是指血液在心脏和全部血管所组成的管道中进行的循环流动。 The current nine-year compulsory textbook “Biology” Volume II, page 39, “The lymphatic circulation” is not considered appropriate. If we can revise it to “lymphatic reflux”, it is more conducive to teaching and more scientific and reasonable. The term “cyclic” is used in its simplest sense to mean that things move or change from time to time. For example, blood circulation refers to the circulating flow of blood in the heart and all blood vessels.
