Instead the glomerulus funnels blood into efferent arterioles which divide into capillaries a second time.

而是由肾小球将液输送进入出球小动，后者分支复成毛细管网。

So with vasodilation of the arterioles, more heat gets lost which, therefore, helps to lower body temperature.

因此，随着动管舒，热量会流失，有助于降低体温。

This is where the arteriole walls develop hyaline deposits, which makes it harder for them to dilate.

这是小动壁形成透明沉积物的地方，使得它们很难扩。

A small alley is as small to the city as an arteriole 0.1 millimeters wide is to you.

一条小巷之于一座城市来说，就像一条0.1毫米的动对你来说一样渺小。

Well in response to low oxygen levels, or hypoxia, the pulmonary arterioles constrict, which raises the pulmonary blood pressure.

为应对低氧水平或缺氧，肺小动会收缩，这就容易引起肺高压。

These arteries eventually branch into the arterioles, the smallest of the arteries.

这些动最终会分支为小动，即最小的动。

We previously learned that arterioles have a smaller diameter than arteries.

我们以前了解到，小动的直径比动小。

If your blood pressure happens to increase, for example, the higher pressure causes the arterioles leading to your glomeruli to stretch.

例如，如果你的压碰巧上升，高的压力会导致导致肾小球的小动伸展。

This process of glycation particularly affects the efferent arteriole and causes it to get stiff and more narrow - a process called hyaline arteriosclerosis.

这种糖基化过程尤其影响出球小动，使其硬化、变窄——该过程叫玻璃样动硬化。

A small alley is as small to the city  as an arteriole 0.1 millimeters wide is to you.

小巷对于城市来说就像0.1毫米的小动对于你来说一样小。

Vasodilation of the arterioles decreases resistance and increases blood flow.

小动管扩减少了阻力，增加了流量。

The cortical radiate arteries continue to divide eventually forming afferent arterioles that split into a tiny bundle of capillaries called the glomerulus.

小叶间动继续分支，最后形成入球小动；后者再分成若干小支形成一团微小的毛细管球，即肾小球。

Just like in the lungs, the aorta branches into arterioles which are smaller arteries and, finally, into capillaries which are the smallest.

就像在肺部一样，主动分叉为小动，最后变为毛细管。

Therefore, we see that the small arterioles are able to provide a significant amount of control over the flow of blood.

因此，我们看到，小动能够提供对液流动的大量控制。

Blood flow to individual organs, or throughout the entire circulatory system, can be regulated by changing the diameter of the arterioles.

流向各个器官或整个循环系统的液可以通过改变小动的直径来调节。

The smallest subdivisions of arteries, the arterioles, have thinner walls in which there are very little connective tissues but relatively more muscle.

动的小分支（小动）携液至最小的管（毛细管）。

On the other end of the capillary bed there's a venule, and the arteriole and venule are usually directly connected by a vessel called the metarteriole.

在毛细管床的另一端，有小静；小动和小静通常是由一种叫后微动的管直接连接的。

Of all of the blood vessels in the body, the most important ones to consider when we talk about resistance to blood flow are the arterioles.

在体内所有的管中，当我们谈到流阻力时，最重要的是动。

For example, if an arteriole constricts, its lumen will decrease in size, but the blood will pass through the arterial with more force or pressure.

例如，如果小动收缩，其管腔大小将减小，但液将以大的力或压力通过动。

In arterioles, a process called hyaline arteriolosclerosis is where the walls of arterioles where they develop hyaline deposits, which are the deposits of proteins, and these make them hard and inflexible.

小动会出现透明样细小动硬化，即小动的管壁上产生了透明质酸沉积，即蛋白质沉积物，而这些物质让小动僵化变硬。
