Red blood cells are roughly the shape of a disk.

红细胞大致呈圆盘状。

Isabelle's body is unable to produce healthy red blood cells.

伊莎贝尔体内无法产生健康的红细胞。

After a pint of blood is collected, it is processed into its transfusible components: plasma, platelets and red blood cells.

采集一品脱血液后，将其加工成可输血的成分：血浆、血小板和红细胞。

That is doubly true of the cells in stored blood since red blood cells become less flexible with age, and thus less able to squish into capillaries.

对于储藏的血液细胞而言更是如此，因为红细胞随着年龄的增长而日益失去弹性，因此就越来越难以挤到毛细血管里。

Hemoglobin, as you know, is an oxygen carrier and so red blood cells concentrate in bags of hemoglobin which circulate in your blood and they carry oxygen.

如你所知，血红蛋白是氧气的载体，所以红细胞集中在血红蛋白的袋子里，血红蛋白在血液中循环，它们携带氧气。
