Now, this might not look like much, but if we were to put a red blood cell up on the screen, it'd be about that big, so these are unbelievably tiny curls.

这可能看起来没什么，但如果我们把红血球细胞放在旁边做对比，就能看出它有多小了，所以这些是微小到极致的蜷缩。

Or, a routine blood test might count too many white cells or elevated liver enzymes.

也可能在常规血验中发现白血球数量过高或肝脏酵素过高。

This is done by using a centrifuge which is a device created to separate fluids.

分红血球要使机，机这种装置就是来分液体的。

White blood cells help your body fight infections.

白血球帮助你的身体抵抗感染。

Uh, mono. - Make that three sources.

是单核血球增多症 -那你就是第三个人了。

We used microscopes to study blood cells in our science class today.

我们天理化课显微镜研究红血球。

Hello, oh, yeah. Hi, Dr. Shiller. Okay, that's my white blood count.

是我。你好，席勒医生。那是我的白血球指数。

Today, a whopping 99% of people living in sub-Saharan Africa have a specific type of a protein receptor on their red blood cells that doesn't allow the parasite to gain entry.

如在非洲撒哈拉以南超过 99% 的人，他们身上的红血球上都有一种特殊的蛋白质受体，这种蛋白质受体会阻止寄生虫进入人体。

This would be like comparing the size of a human red blood cell to the entire island of Sicily; an incredible difference in scale that's difficult to really wrap your head around.

这就好比把一个人类红血球的大小与整个西西里岛的大小进行比较；规模相差悬殊，难以让人真正理解。

Participants in these studies wear a special sensor that uses spectroscopy to measure near-infrared light absorption; you see, red blood cells absorb light differently when they're carrying a lot of oxygen.

这些研究的参与者会戴上一个特殊的传感器，它使光谱来测量近红外光的吸收；你看，红血球携带大量氧气时吸收光的方式不同。

We only exist as the blood corpuscles that course through its arteries, and if it could work without us, it would let us die.

我们存在着，只不过像流过它的大动脉的一些血球，要是它没有我们也能工作的话，它就会让我们死掉。

Even the ones that swim hard enough and manage to reach the uterus may then be culled by defending resident white blood cells.

即使是那些游得足够努力并设法到达子宫的白血球也可能被保护常驻白血球而被剔除。

So is the microscopic examination for blood corpuscles. The latter is valueless if the stains are a few hours old.

显微镜检验血球的方法也同样不好。如果血迹已干了几个钟头以后，再显微镜来检验就不起作了。

They can do this because inside the red blood cells, there is a very important molecule called haemoglobin.

它们之所以能做到这一点，是因为在红血球内部，有一种非常重要的分子，叫做血红蛋白。

When the white blood cells die, they, combined with the dead skin and sebum, create the pus-filled pimple.

当白血球细胞死去时，它们再加上死皮和皮脂，就会造成化脓的痘痘。

And there are not enough red blood cells to transport nutrients and oxygen.

而且没有足够的红血球来运输营养和氧气。

To create the sample, the patient's red blood cells need to first be separated.

要生成该样本，首先要分患者的红血球。

The blood cells are mainly red blood cells also called RBCs or erythrocytes.

血细胞主要是红细胞，也叫 RBCs 或红血球。

Your immune system responds by sending blood to the area, giving the appearance of redness and inflammation, and white blood cells come to the site, too, to clear up the infection.

你的免疫系统输送血液到那区块来作响应，造成红肿和发炎的样子，接着白血球细胞也会来到这个位置来清除感染。

Vitamin A helps make white blood cells, key in the body's defense, helps shape bones and improves vision by keeping the cells of the eye in check.

维他命A有助于白血球的形成，它们是身体防御的关键，帮助骨骼塑形并通过控制眼球细胞来提高视力。
