They basically are the endothelium, the inside lining of the blood vessel floating around.

它们基本上是内皮，漂浮在周围内层。

Cortisol can also cause the endothelium, or inner lining of blood vessels, to not function normally.

压力荷尔蒙皮质醇会令你内循环或中内覆组织无法正常运行。

The first way is called the extrinsic pathway, which starts when tissue factor gets exposed by the injury of the endothelium.

第一种是外源性凝途径由组织暴露于壁损伤处后启动。

It also releases Sphingomyelinase C toxin, which destroys red blood cells as well as the endothelium of the capillaries, causing hemorrhage.

它也能释放出鞘磷脂酶C，破红细胞和内皮细胞，从而导致出。

During stasis, platelets and other clotting factors contact the endothelium, and prolonged interaction leads to clotting factor adhesion, and, ultimately, activation of the clotting cascade.

当流瘀滞发生时，小板、其他凝、内皮细胞长时间互相作用，最终导致凝级联反应激。

After that, some platelets adhere to the damaged vessel wall, and become activated by collagen and tissue factor, proteins which are normally kept separated from the blood by an intact endothelium.

接着，小板粘附至损伤壁，并且被胶原和组织化；这些蛋白质平常由完好壁与液隔离。

Finally, there's the innermost layer of the heart called the endocardium, which is made of a relatively thin layer of endothelium which is the same layer of cells that line the blood vessels.

最后，心脏最内层叫心内膜，由一层较薄内皮细胞构成；与位在内壁是同一层细胞。

Normally, after a cut and damage to the endothelium, or inner lining of blood vessel walls, there's an immediate vasoconstriction or narrowing of the blood vessel which limits the amount of blood flow.

正常情况下，壁内层内皮细胞受到损伤后，会立刻收缩变窄，减少流量。

The cool thing about this layer is that it contains the endothelium, which you may remember is made up of simple squamous epithelium tissue and is continuous with the lining of the heart.

这层最酷地方是它包含内皮，你可能记得内皮是由简单鳞状上皮组织组成，并且与心脏内膜连续。

Normally, the process starts with damage to the endothelium, or inner lining of blood vessel walls, after which there's an immediate vasoconstriction or narrowing of the blood vessel which limits the amount of blood flow.

通常，这一过程开始于内皮损伤，之后立即发生收缩，或者说通过收缩来限制流量。

The moment the endothelium, that is the inner lining of the red blood vessel, when it feels injury, it sends a whole cascade of markers and signals and say, " Yo, I'm like, I'm cut here."

那一刻内皮，也就是红色内层，当它感觉到受伤时，它会发送一连串标记和信号说，“哟，我就像，我这里被割伤了。”
