The valves that separate the ventricles from the blood vessels leaving the heart are called the semilunar valves.

将心室和离开心脏的血管分开的瓣膜称为半月形瓣膜。

Before we formally introduce this major blood vessel leaving the heart, let's visit Mr. Smith's very busy widget factory.

在我们正式介绍离开心脏的主要血管之前，我们参观一下史密斯先生非常繁忙的小部件工厂。

These valves are called the semilunar valves and they separate the ventricles from the blood vessels leaving the heart.

这些瓣膜称为半月瓣膜，它们将心室与远离心脏的血管分开。

However, the end-systolic volume can vary due to a number of factors, such as how forcefully the ventricles contract and how much pressure already exists in the blood vessels leaving the heart.

然而，收缩末期容积可能会因许多因素而变化，例如心室收缩的力度和离开心脏的血管中已经存在的压力。

So when levels of glucose are super high in the blood (meaning it's a hyperosmolar state), water begins to leave the body's cells and enter the blood vessels, leaving the cells relatively dry and shriveled rather than plump and juicy.

所以当血糖水平特别高时，意思是它在一种高渗状态，水逐渐离开细胞进入到血管里，这让细胞变得干燥皱缩，而不是丰满多汁的。
