Parenchyma cells are the most common ground tissue cell type in a plant.

薄壁细胞是植物中最常见的基质组织细胞类型。

Turns out there are about eight times more microorganisms in your gut as tissue cells in your body.

事实证明，肠道中的微生物数量是体内组织细胞数量的八倍。

Between the follicles is the stromal or connective tissue cells, and lining the ovary is a layer of epithelial cells.

卵泡之间的物质是基质细胞，也是结缔组织细胞，卵巢的内侧排列着一层上皮细胞。

And your white blood cells, or leukocytes that scour your circulatory system fighting off infection, they're connective tissue cells, too.

你的白细胞，或者说白细胞在你的循环系统中抵抗感染，它们也是结缔组织细胞。

And without blood, the tissue cells start to die.

没有血液, 组织细胞开始死亡。

Instead, immune cells need to be able to squeeze through gaps between tissue cells and pick the best route.

相反，免疫细胞需要能够挤过组织细胞之间的缝隙并选择最佳路线。

There's also neurofibromatosis, or Nf, which has three different types, but is generally a genetic disorder that mainly affects nerve cell tissues.

还有神经纤维瘤病或 Nf， 它有三种不同的类型，但通常是一种主要影响神经细胞组织的遗传性疾病。

BUT! There is another class of connective tissue cells that are responsible for an equally important role. And that is: protecting you, from pretty much everything.

但是，还有另外一类结缔组织细胞也起着同样重要的作用，那就是：保护你不受几乎所有东西的伤害。

In the organs, the red blood cells line up alongside tissue cells and drop off oxygen, as well as pick up carbon dioxide basically the reverse of what happens with the alveolus in the lung.

在器官中，红细胞与组织细胞排列在一起，并释放氧气，同时吸收二氧化碳；基本上与血液在肺泡处的情况相反。

The immune system is made up of organs, tissues, cells, and molecules that all work together to generate an immune response that protects us from microorganisms, removes toxins, and destroys tumor cells - hopefully not all at once!

免疫系统由免疫器官、免疫组织、免疫细胞以及分子组成它们共同协作，从而产生了能够保护我们的免疫反应，来抵御微生物、去除毒素和杀灭肿瘤细胞；愿敌军们别一起搞突袭！
