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

它们基本上，漂浮在周围的血管的层。

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

压力荷尔蒙质醇会令你的循环或血管中的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.

第一种性凝血途径由组织因子暴露于血管壁损伤处后启动。

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，破红胞和血管胞，从而导致出血。

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.

当血流瘀滞发生时，血小板、其他凝血因子、胞长时间的互相作用，最终导致凝血级联反应的激活。

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，血小板粘附至损伤的血管壁，并且被胶原和组织因子活化；这些蛋白质平常由完好的血管壁与血液隔离。

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，心脏的最层叫心膜，由一层较薄的胞构成；与位在血管壁的同一层胞。

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，血管壁层的胞受到损伤后，血管会立刻收缩变窄，减少血流量。

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.

这层最酷的地方它包含，你可能记得由简单的鳞状上组织组成的，并且与心脏膜连续。

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，这一过程开始于血管损伤，之后立即发生血管收缩，或者说通过收缩血管来限制血流量。

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，也就红色血管的层，当它感觉到受伤时，它会发送一连串的标记和信号说，“哟，我就像，我这里被割伤了。”
