你的問題是為什么血紅蛋白在紅細(xì)胞而不在血漿中.
這是因?yàn)橐话阏f來血漿就是我們所說的血液,而血紅蛋白是我們身體的所需O2的載體,其由造血干細(xì)胞分化而來,存在于血細(xì)胞中.而血漿中,除了血細(xì)胞以外,還有大量的水,纖維蛋白原（凝血用）,血小板（纖維蛋白原在傷口處合成纖維蛋白,就像給傷口處編了一張網(wǎng),而血小板就是填充物,填補(bǔ)缺口）等等；而我們說的血清就是沒有纖維蛋白原的血漿.

This is because the plasma in general is what we call blood,and hemoglobin is required for our physical carrier O2,and its differentiation from hematopoietic stem cells from cells found in blood.And plasma,in addition to blood cells,there are a lot of water,fibrinogen (clotting purposes),and platelets (fibrinogen synthetic protein in the wounds,as to the wounds for a network,and platelet fillers is to fill the gap) and so on; and what we are arguing is that there is no serum plasma fibrinogen
