So there's two sets of pleura.

这里有两组胸。

Then the whole thing is surrounded by like a Saran Wrap called the pleura, which holds the whole thing together.

然后整个组织被一个叫做胸的保鲜包裹着，它把整个组织固定在一起。

The pleura, by the way, is the lining that covers the lungs.

顺便说一句，胸是覆盖肺部的内层。

The visceral pleura surrounds the outside of the lung.

胸层包围着肺的外部。

The parietal pleura lines the inside of the chest wall and extends over the diaphragm.

胸层位于胸内侧，延伸至膈肌上方。

The pleural cavity or pleural space lies between the parietal pleura which is stuck to the chest wall and the visceral pleura which is stuck to the lungs.

胸腔位于层胸与层胸之间，层胸贴附于胸，层胸贴附于双肺。

The visceral or pulmonary pleura covers the outside of the lungs, and the parietal or costal pleura lines the inside of the chest wall, and it extends over the top of diaphragm.

层胸或肺胸覆盖肺的外部，层胸或肋胸排列在胸的内部，并延伸到横膈的顶部。

In recent years, scientists have hotly debated whether the body tissue came from the top of the insect, known as the notum, or the side of the body, known as the pleura.

近年来，科学家们一直在激烈争论身体组织是来自昆虫的顶部，即 notum， 还是来自身体的侧面，即胸。

If there were no way out of the pleural space, then it would fill up with fluid, but fortunately, there are lymphatic vessels in the pleura that drain the fluid away and deliver it back into the circulatory system.

如果没有从胸腔出来的途径，那么液体将填满这个间隙，不过幸好，胸里的淋巴管能将液体引流出胸腔，并送回循环统。
