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膜的保鲜膜包裹着，它把整个组织固定在一起。

Just like an abscess, the infected pleural space can develop fibrinous walls and have loculations.

像脓肿一样，被感染的胸膜腔能形成纤维壁和多个小腔。

Each pleural cavity is lined by a pleural membrane that is composed of two layers.

每个胸膜腔由两层脏壁构成的胸膜层构成。

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

顺便说一句，胸膜是覆盖部的内层。

In summary, each pleural cavity is defined by a space surrounding each lung and lined by a pleural membrane.

总之，每个胸膜腔由包饶和胸膜层间的间隙构成。

The lower intrapleural pressure outside the lungs creates a vacuum that keeps the lungs expanded and prevents them from collapsing.

外较低的胸膜腔内产生真空环境，使保持扩张，防止塌陷。

In order to understand how we breathe, we need to understand the different spaces and pressures within our thoracic cavity.

了解人体呼吸机制前，我们需要理不同的间隙与解胸膜腔内的。

The intrapleural pressure is the pressure within the pleural cavity and it is always less than intrapulmonary pressure, which is the pressure inside the lung.

胸膜腔内指胸膜腔内的，内指内的，胸膜腔内始终小于内。

Alright, as a quick recap - a pleural effusion is when fluid collects in the pleural space around the lungs, restricting expansion and causing pain and difficulty breathing.

得！快速回顾一下：胸腔积液是指液体汇聚于包绕在周围的胸膜腔内，限制扩张，造成胸痛和呼吸困难。

The pressure within this pleural cavity is referred to as the intrapleural pressure, and it is less than the intrapulmonary pressure - that's the pressure within the lungs.

这个胸膜腔内的被称为胸膜内，它小于内——内。

Small transudative pleural effusions resulting from heart failure may be treated with diuretics and sodium restriction, whereas larger pleural effusions due to an oncologic process might require draining with a tube.

对于心衰竭形成的少量漏出液，可给利尿剂及限制钠盐摄入，而对于由肿瘤侵犯胸膜导致的大量胸腔积液，则可能需要插管引流。

This pressure gradient between the lungs and the pleural cavity is referred to as transpulmonary pressure and creates a vacuum effect that is necessary to keep the lungs expanded at all times.

和胸膜腔之间的这种梯度被称为经，产生真空效应，这是保持始终扩张所必需的。

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.

脏层胸膜或胸膜覆盖的外部，壁层胸膜或肋胸膜排列在胸壁的内部，并延伸到横膈膜的顶部。

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.

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