我想問呢` blood cells 系吾系 系plasma入面咖?
書寫: Blood consists of RBCs WBCs platelets in a liquid called plasma.
plasma 有nutrients 同blood cells
blood有plasma(nutrients) 同blood cells
有既野都相同 甘又有咩必要分開吾同名

睇番阿sir派既wk sheet
佢寫blood 入面有2部分 ( plasma & blood cells )
甘blood cells又系吾系包含系plasma入面?
點解同書有出入-.-?

✔ 最佳答案
其實係blood係分左兩個components
plasma同blood cells
如果你用離心機就會分開到呢兩種野

我本書係寫:
blood is a liquid tissue consisting of blood cells which float in a straw-coloured fluid,the plasma.

你可以當血係一碗拉麵,固體ge麵係RBS,WBS同血小板,液體ge湯係plasma,鹽、糖等水溶性調味料係營著同廢物,咁樣理解,兩者絕對係冇矛盾

1)對比:
Blood consists of RBCs WBCs platelets in a liquid called plasma V.S. 拉麵包含麵同浸住麵ge湯
2)再對比
blood 入面有2部分 ( plasma & blood cells ) V.S. 拉麵入面有2部分 ( 麵同埋湯)

有矛盾?
