留美老師帶你每日說英文 第456期:血液的作用

padding-bottom: 65.5%;">

臺灣籍旅美老師今天交給我們的句子是：

Blood is the tissue that not only carries cells that transport oxygen, for example, the red blood cells, or fights infectious diseases, but it also carries messenger molecules, hormone-like factors that transport information from one cell to another, from one tissue to another, including the brain.
血液不只是夾帶例如紅血球這樣的輸氧細胞的組織，或是抵抗傳染病，同時也夾帶了像荷爾蒙這樣的訊息因子，從一個細胞到另一個細胞，一個組織到另一個組織，在大腦裏也一樣。
