They also have air sacs that go into their body.

它们体内也有气囊。

Dinosaurs used air sacs to move air along their massive necks. Birds use air sacs to stay aloft for long periods.

恐龙利用气囊使空气在庞大的颈部流动。鸟类利用气囊保持长期高空飞行。

Your lungs are like sponges that are made of tiny air sacs.

你的肺脏就像海绵，由许多小小气囊组成。

At the end of each branch is a tiny air sac called an alveolus.

在每个分支的末端都有一个叫做肺泡的小气囊。

Like the theropods, these titans used air sacs to breathe and had light, hollow bones.

像兽脚亚目类恐龙一样，这些巨人使用气囊来呼吸，而且有很轻的中空骨骼。

The air sacs also help the primates avoid hyperventilating, which means to breathe an unusually fast rate.

气囊还帮助灵长类动物避免过度呼吸（呼吸速度异常快）。

Walruses have an air sac under their throat, which helps them float vertically in the water and sleep.

海象的喉咙下面有一个气囊，帮助它们在水中垂直漂浮和睡觉。

That problem happens deep in the lungs, in tiny air sacs called alveoli, which exchange carbon dioxide for oxygen.

这个问题出现在肺部深处，叫做肺泡的微小气囊中，肺泡是将二氧化碳转化为氧气的部位。

The air comes in through the windpipe, gets spread out throughout the lung in a bunch of air sacs.

空气从气管进来，在肺部散开形成一堆气囊。

Ornithischian dinosaurs like Triceratops and Stegosaurs lack these air sacs and as a result, most of them weren't very big.

三角龙和剑龙属于鸟臀目恐龙，缺少这些气囊，因此它们大多数的体型并不大。

It then fills the alveoli, tiny air sacs that enable the exchange of oxygen and carbon dioxide between the lungs and blood.

然后填充肺泡，微小的空气囊能使氧气和二氧化碳在肺部和血液之间交换。

The alveoli are tiny air sacs that look like tiny clumps of grapes, that are wrapped up in a net of capillaries.

肺泡是微小的气囊，看起来像小丛葡萄，包裹于毛细血管网中。

The researchers said humans also lack balloon-like structures called air sacs that may help some apes and monkeys produce loud, deep calls.

研究人员说，人类也缺乏称为气囊的气球状结构，这种结构可能有助于一些类人猿和猴子发出响亮而深沉的叫声。

So if you vape and you are unlucky and get vaping-associated lung injury, inflammation happens and the air sacs fill up with stuff.

所以如果你吸电子烟，而且你很不幸，受到了与电子烟相关的肺部损伤，就会产生炎症，气囊就会充满东西。

They clog the delicate air sacs, making breathing even harder.

它们会堵塞脆弱的气囊，使呼吸更加困难。

Both are bipedal and both have hollow bones containing air sacs.

两者都是双足动物，并且都有包含气囊的中空骨骼。

They lie right next to the microscopic air sacs of your lungs.

它们位于肺部微小气囊旁。

Their skeletons had a special feature that mammals lacked: a sophisticated system of air sacs.

它们的骨骼有一个哺乳动物所没有的特殊特征：一个复杂的气囊系统。

Additionally, dinosaurs, like birds, often had extensive air sac systems throughout their bodies.

此外，像鸟类一样，恐龙的全身通常都有广泛的气囊系统。

For example, a simple squamous epithelium refers to a single layer of flat, scale-like cells, like the lining of the air sacs deep in your lungs.

例如，简单的鳞状上皮是指单层平坦的鳞片状细胞，就像肺部深处的气囊内膜一样。
