Gastrointestinal tract跟
Alimentary canal差在哪阿
前面課本寫說是
Single elongated tube lined by epithelial cells that associate with digestion wit
h entry and exit ends
後面說是
The organs that food and liquids travel through when they are swallowed, digeste
d, absorbed, and leave the body as feces
阿不就都看起來都在講消化道
為什麼要分成兩個寫
說vertebrate digestive system consist alimentary canel or gl tract
你版有人知道這兩個詞差在哪嗎
還是只是同樣的東西不同說法
