When you have anemia, your body doesn「t have enough red blood cells, or your red blood cells don」t contain enough hemoglobin.

当你患贫血癥的时候你的身体没有足够的红血球，或你的红血球不含足够的血红蛋白。

In the presence of a strong magnetic field, the red blood cells form chains that align themselves with the field lines where convoys of red blood cells line up behind a leading cell.

在强磁场的影响下，红细胞会顺着磁场线的方向排列成细胞链，其中会有若干红细胞在领头细胞之后排列成一队。

If not treated promptly with effective medicines, malaria can kill by infecting and destroying red blood cells and by clogging the capillaries that carry blood to the brain or other vital organs.

如不用有效药物给予及时治疗，疟疾可通过感染和摧毁红血球以及阻塞将血液输送到大脑或其它重要器官的毛细血管引起死亡。

Humans and dolphins have the largest brains of all mammals and both have red blood cells that are exceptionally permeable to glucose and able to ferry large amounts of the sugar into the brain.

在所有哺乳动物中，人类和海豚的脑最大。而且，人和海豚的血液中都有红细胞，特别利于葡萄糖通过，并能将大量的糖运送到脑部。

But platelets obtained from donated blood have several drawbacks, including a shelf life of only 5 days — versus 6 weeks for red blood cells — and a risk of bacterial infections.

然而，来自捐献血液的血小板有几个缺点，其中包括：保存期限只有5天(而红细胞的保存期限为6周)，而且有感染细菌的危险。

Nevertheless, the microscope can pick out objects just 1.2 micrometers across – red blood cells are typically 6 to 8 micrometers across.

不过，这种显微镜已经能够测量1.2微米的物体，相比较红细胞典型在6至8微米左右。

In APL, there is a drop in the production of normal red blood cells and platelets, resulting in anemia and thrombocytopenia. The bone marrow is unable to produce healthy red blood cells.

由于骨髓无法生成健康的红细胞，急性骨髓性白血病患者的正常红细胞和血小板会减少，导致病人出现贫血和血小板过低的癥状。

And 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.

对于储藏的血液而言，情形更是如此，因为红细胞随年龄增长而日益失去灵活性，也就越来越难以挤到毛细血管里。

Malaria kills its victims by damaging red blood cells and clogging capillaries that feed the brain and other organs.

疟疾通过损坏红细胞、阻塞通往大脑和其他器官的毛细血管，把感染者置于死地。

Carbon monoxide binds to red blood cells more easily than oxygen, so it limits the amount of oxygen blood carries through the body.

相比氧气，一氧化碳能更容易地结合血红细胞，从而阻碍血液携带氧气流经全身。

Anemia is a condition in which you don「t have enough healthy red blood cells to carry adequate oxygen to your tissues. Having anemia may make you feel exhausted.

贫血是机体红细胞减少，不能对组织器官充分供氧的一种病理状态。此时常常会有精疲力竭的感觉。

Anemia is a condition in which you don」t have enough healthy red blood cells to carry adequate oxygen to your tissues.

贫血是机体红细胞减少，不能对组织器官充分供氧的一种病理状态。

Iron is an essential component of haemoglobin a substance in red blood cells that carries oxygen around the body.

铁是血红蛋白重要的组成部分之一，足量的血红细胞运送着人体内必须的氧。

Healthy red blood cells have an average lifespan of 120 days, so when they die, the iron from the hemoglobin is recycled to make new red blood cells.

健康血红细胞的平均寿命是120天，当他们衰亡以后，血红蛋白中的铁被重新利用来产生新的血红细胞。

The anaemia develops in those whose red blood cells contain a particular type of haemoglobin, the protein that carries oxygen.

贫血癥发于那些红血球中含有一种特殊的血红蛋白，其蛋白质中含有氧气的人。
