输乳管

结果每一导管系统均由一输乳管反复分支而成，Y型分支占90%以上，最多为6分支型；

Results Every mammary duct system are made up by many times bifurcated branches of lactiferous duct as a duct tree . 90 % of the bifurcation was Y shape , rarely with 6 bifurcated branches .

研究者运用了显微解剖技术来分离每个标本中的微输乳管。

The researchers used microdissection techniques to isolate tiny milk ducts in each sample .

结果：每个输乳管均呈树状分支，构成1个导管系统。

Results : each input duct showed a uniform tree branches to form a duct system .

以输乳管为第1级，常见的为9级分支结构，最多可达16级分支。

输乳管在乳头处较为狭窄，继之膨大为壶腹，称为输乳管窦，有储存乳汁的作用。
