So, when a germ gets inside and attacks your body, the immune system sees unusual foreign shapes on the surface, and then special cells in your body called white blood cells create antibodies that connect up.

所以，当细菌侵入并你的身体时，你的免疫系统就发现这些外观上不寻常的异物，然后你身体中的特殊细胞，即白细胞，连接起来的抗体。

Well, antibodies are made by white blood cells called b lymphocytes.

抗体是由一种叫做 b 淋巴细胞的白细胞的。

Hematopoiesis is the process of forming white blood cells, as well as red blood cells, and platelets and it takes place in the bone marrow.

造血是白细胞、红细胞和血小板的的过程，发在骨髓中。

Because alveoli serve as critical exchange points between the blood and air from the outside world, they have their own specialized types of white blood cells, or macrophages, which defend against foreign organisms by enveloping and eating them.

因为肺泡相当于血液和来自体外的空气之间的一个临界交换点，们拥有专门的白血细胞，又名巨噬细胞，这种细胞通过包络和噬外来细胞来进行防御。

The red color produces white and red blood cells.

红色部分白细胞和红细胞。

STEP 12 Get plenty of rest. Stress increases the amount of the hormone cortisol in your body, which can interfere with the white blood cells that fight off infections.

获得充足的休息。压力增加体内的荷尔蒙皮质醇的水平，干扰抵抗感染的白细胞。

The white cell count is raised in cases of infection.

有感染时，白细胞数升高。

A week after exposure, the victim's white blood cells create antibodies.

感染一周后 患者的白细胞分泌出抗体。

For some diseases, the immune system uses white blood cells and antibodies to attack it.

对于某些疾病，免疫系统使用白细胞和抗体来。

For example, with red blood cells you've basically got to plunge it straight into liquid nitrogen for it to survive, whereas with white blood cells you have to cool it really, really slowly to get the same effect.

举个例子，对于红细胞，你基本上要把直接插入液氮中才能存活，而对于白细胞，你必须非常非常缓慢地冷却才能达到同样的效果。”

Blood consists of the nutrient and the heat-transporting plasma, the oxygen-carrying red blood cells, and then less than one percent is made up of a very important pathogen fight in white blood cells.

血液由营养物质和传递热量的血浆，携带氧气的红细胞组成，然后不到 1% 是由白细胞中非常重要的病原体组成的。

“So this suggests that the initial encounter of the very type of white blood cell that we think defends us against the virus may be taken out by this initial wave of infection.”

“所以，这就说明我们之前认为能帮助我们防御病毒的这种白细胞可能被第一波感染杀死。”

So then, your immune system kicks in, sending over a bunch of white blood cells, and the result is inflammation, maybe even pneumonia, or scarring of the lung tissue.

然后呢，你的免疫系统就开始发挥作用了，传递一堆白细胞，结果就是发炎，甚至严重的话得肺炎，或者是给肺部组织造成伤疤。

As neutrophils infiltrate and die off, they make their way through the urinary tract, and are peed out; so people with acute pyelonephritis often have white blood cells in their urine.

随着中性粒细胞浸润、死亡，其通过尿道排出体外，因此，急性肾盂肾炎的患者通常尿中可查见白细胞。

The first T cell lymphoma is adult T-cell lymphoma, but it's sometimes referred to as a leukemia because the abnormal white blood cells or leukocytes often get into the bloodstream.

第一类T细胞淋巴瘤是成人T细胞淋巴瘤，但有时也被认为是白血病，因为异常的白细胞经常进入血液。

In reality, if you eat this, it will dramatically lower your blood pressure, cause heart arrhythmia, and stop the production of white blood cells, so it will kill you.

事实上，如果你吃这个，大幅降低你的血压，导致心律失常，停止白细胞的，所以杀死你。

This inflammation and local pain's ultimately caused by white blood cells, or leukocytes, which migrate to the site to help eliminate uric acid and release proinflammatory chemicals, including cytokines.

炎症和疼痛根本上都是由白细胞引起的；白细胞从血液迁移至关节腔，帮助清除沉积的尿酸，并释放大量的炎症因子，包括细胞因子。

This causes hypersplenism, meaning the spleen traps blood elements like red blood cells, which causes anemia, and white blood cells, which can cause leukopenia, or platelets, causing Thrombocytopenia.

这造成脾功能亢进，即脾困住血液成分，比如红细胞，造成贫血；以及白细胞，造成白细胞减少；或者血小板，造成血小板减少。

The University of Arizona's biology department explains on its website that T-cells are a type of white blood cell and are made in our bone marrow.

亚利桑那大学物系在其网站上解释称，T细胞是一种白细胞，来源于骨髓。

The device uses just a drop of blood. It separates the white cells from the red cells which carry oxygen. It then counts the CD4 cells immediately.

该设备只需要一滴血，将白细胞与携带氧的红细胞分开，然后立即清点CD4细胞的数量。
