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.

最层者称为膜，有皮构成；它们形成表面，使血液流经时的摩擦降到最低。

A dissection is where the inner wall, or intima, gets a tear, and blood tracks into a false lumen in the vessel wall.

动脉壁或者说膜产生撕裂，血流随之进入管壁的假腔中。

Both the cells of the tunica intima and tunica media generally get the nutrients they need from the blood in the lumen.

膜中膜的，都能从管腔的血液中获取所需的营养物质。

Surrounding the tunica intima is the middle layer, the tunica media, made of smooth muscle cells and sheets of the protein elastin.

围绕膜的是中间层，中膜，由平肌蛋白质弹性蛋白片组成。

Anatomists call these layers " tunics, " and the innermost section is the tunica intima — which should be pretty easy to remember because, you know, it has like intimate contact with the lumen. It's like your circulatory underpants.

解剖学家称这些层为束腰外衣，最里面的部分是膜——这应该很容易记住，因为，你知道，它腔有亲密的接触。就像你的循环裤。

So what you can do, there's databases now that we call carotid intima media thickness.

那么，你可以做的是，现在有一些数据库，我们称之为颈动脉膜中层厚度。

Capillary walls are made of just a single layer of epithelial tissue, which form only the tunic intima, so they're able to deliver the oxygen and other nutrients in your blood to their cellular destinations through diffusion.

毛血管壁仅由单层上皮组织组成，仅形成被膜膜，因此它们能够通过扩散将血液中的氧气其他营养物质输送到目的地。
