Those without endothelial cells failed to create a network of blood vessels.

而如果没有内皮细胞，就无法形成血管网络。

These changes make the endothelial lining more likely to develop blood clots or aneurysms.

这些变化使得内皮细胞内壁更容易形成血栓或动脉瘤。

These areas are lined with endothelial cells surrounded by smooth muscle.

这些间隙内排列有平滑肌围绕的内皮细胞。

These toxins cause endothelial cell damage which creates inflammation along the inner lining of arteries.

这些毒素可以导致内皮细胞损伤，从而引起动脉内壁炎症。

Another consequence of portal hypertension is that the endothelial cells lining the blood vessels release more nitric oxide.

门静脉高压症的另一种后果是血管内皮细胞会释放更多的一氧化氮。

Hypertension causes wear and tear in the endothelial cells, and decrease their ability to produce nitric oxide.

高血压会导致内皮细胞的磨损，降低内皮细胞产生一氧化氮的能力。

Lymphatic capillaries are extremely permeable because their walls are made of endothelial cells that only loosely overlap, forming one-way minivalves.

毛细淋巴管是极度通透的，因为它们的管壁仅由松散重叠的内皮细胞构成，形成单向的微小瓣膜。

These then get into the mother's circulation and cause the endothelial cells that line her blood vessels to become dysfunctional.

之后它们进入母体的血液循环，导致血管表面的内皮细胞功能障碍。

A third factor is damage to the endothelial cell lining of a blood vessel which exposes tissue factor and collagen.

第三个因素是血管壁的损伤，这使得组织因子和胶原得以暴露。

Finally, endothelial injury increases vascular permeability, allowing water to slip out of blood vessels between neighboring endothelial cells and get into the tissues.

最后，内皮损伤还可使血管通透性增加，导致水分通过相邻内皮细胞间隙从血管漏出并进入周围组织。

To do this, the pathogens typically have to bind to surface receptors on the endothelial cells in order to get across.

要做到这一点，病原体通常必须结合到内皮细胞的表面受体以实现跨越。

These medications inhibit the PDE-5 enzyme in endothelial cells which normally breaks down cGMP, leading to higher levels of cGMP.

这些药物抑制内皮细胞中的PDE-5酶，而PDE-5酶通常用来降解cGMP；药物作用下，细胞内cGMP水平升高。

On the other side of the pneumocytes are endothelial cells that line the capillary walls, which is what holds the blood.

而肺泡细胞的另一边就是毛细血管壁的内皮细胞，毛细血管携带的便是我们亲爱的血液。

Meanwhile, lipid- or fat-soluble molecules, like oxygen and carbon dioxide, can dissolve and then diffuse across the endothelial cell membranes.

同时，脂质或脂溶性分子，如氧气和二氧化碳，可溶解并通过内皮细胞膜扩散。

Now, regardless of type, Kaposi's sarcoma is an endothelial cell neoplasm, so it causes vascular proliferation, resulting in dark or violaceous plaques.

无论何种类型的卡波西肉瘤，都是一种内皮细胞瘤，因此它会引起血管的增殖，导致黑色或紫色斑块。

The three main causes: stasis, hypercoagulation of clotting factors, and damage of the endothelial lining are often referred to as Virchow's triad.

三大危险因素包括血流瘀滞、高凝状态、内皮损伤，被称为Virchow三角理论。

Eventually, the threads actually pull the opposite sides of the wound together, to close the vessel wall, so the endothelial cells can be replaced.

最终，这些线实际上把伤口的相对两侧拉在一起，关闭血管壁，所以内皮细胞可以被替换。

Blood-brain barrier is a tightly packed layer of endothelial cells that restricts free access of molecules between the blood and the brain.

血脑屏障是一层紧密堆积的内皮细胞，它限制了自由出入血液和大脑之间的分子。

This respiratory surface, also known as the respiratory membrane, includes the alveolar epithelial cells as well as the pulmonary capillary endothelial cells.

呼吸表面，也称为呼吸膜，包括肺泡上皮细胞和肺毛细血管内皮细胞。

The innermost tunic is called the tunica intima, which includes the endothelial cells, which create a slick surface that minimizes friction for blood moving through it.

最内层者称为内膜，有内皮细胞构成；它们形成了光滑表面，使血液流经时的摩擦降到最低。
