Some of our largest artery walls are made of this stretchy elastic tissue, too, which provides both support and flexibility.

我们一些最大的动脉壁也是由这种有弹性的弹性组织制成的，它提供了支撑和灵活性。

That's where you'll find dense elastic tissue — for example, connecting your vertebrae so that your spine can curve and twist.

你会发现致密的弹性组织。比如说连接你的椎骨，这样你的脊柱可以弯曲和扭转。

Today we wrapped up our four-episode series on tissues, with a survey of the sub-groups of loose and dense connective tissue, including areolar, adipose, reticular, tendons, ligaments, dense irregular, and dense elastic tissue.

今天我们总结了关于组织的四集系列，调查了松散和致密结缔组织的亚群，包括蜂窝、脂肪、网状、肌腱、韧带、致密不规则组织和致密弹性组织。

Veins are thinner-walled than arteries. They conduct waste-filled blood toward the heart from the tissues. Veins have little elastic tissue and less connective tissue than arteries.

与动脉相比，静脉血压极低。最小的静脉称为微静脉，由毛细血管汇集而成。
