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脉，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，随着动脉管舒张，更多热量会流失，有助于降低体温。

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

条小巷之于座城市来说，就像条0.1毫米宽的动脉对你来说样渺小。

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

这是小动脉壁形成透沉积物的地方，使得它们很难扩张。

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，小动脉会收缩，这就容易引起压。

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

这些动脉最终会分支为小动脉，即最小的动脉。

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，更的压力会导致导致肾小球的小动脉伸展。

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

我们以前了解到，小动脉的直径比动脉小。

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毫米宽的小动脉对于你来说样小。

Vasodilation of the arterioles decreases resistance and increases blood flow.

小动脉管扩张减少了阻力，增加了流量。

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脉，使其硬化、变窄——该过程叫玻璃样动脉硬化。

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

就像在部样，主动脉分叉为小动脉，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，小动脉能够提供对液流动的大量控制。

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

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

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

动脉的小分支（小动脉）携液至最小的管（毛细管）。

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脉的直径来调节。

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.

在毛细管床的另端，有小静脉；小动脉和小静脉通常是由种叫后微动脉的管直接连接的。

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，如果小动脉收缩，其管腔大小将减小，但液将以更大的力或压力通过动脉。

So that blood goes from the pulmonary artery into a pulmonary arteriole, which is a little bit smaller and, finally, into a capillary which is the smallest.

液从动脉进入较细小的小动脉，最后进入毛细管。

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，最重要的是动脉。
