Once it's passed the pulmonary valve, the blood goes into the pulmonary arteries, which carry blood away from the heart to the left and right lung.

一旦血液通过肺动脉瓣，便会进入肺动脉；肺动脉将血液从心脏输送到左肺和右肺。

The left lung contains what we call the cardiac notch, as the heart takes up this space within the thoracic cavity.

左肺包括我们称为是心脏切记的位置，因为心脏在胸腔内占据这个空间。

Well, the reason is is that the left lung has to make space for the heart because the heart sits in the left side of the chest.

原因是左肺必须为心脏腾出空间，因为心脏位于胸部的左侧。

In this case, a nodular mass is visible in the inferior, lateral, and anterior left lung, meaning it's most likely within the anteromedial basal subsegment of the lower left lobe.

在如图病例中，可看到左肺前下部有结节状肿物，意味着它很可能位于左下肺叶的前基底段。

They then enter the lungs, and the right lung has three lobes - upper lobe, middle lobe, and lower lobe, and the left lung has just an upper lobe and lower lobe.

然后接着看肺部，右肺有三叶：上叶、中叶和下叶；左肺只有两叶，即上叶和下叶。

The right lung, which is the slightly larger of the two, is divided into three lobes, or divisions, and the left lung is divided into two lobes.

However, a second chest radiograph from the night of hospital day 5 (illness day 9) showed evidence of pneumonia in the lower lobe of the left lung (Figure 4).
