It is a large depressed area that lies near the centre of the medial surface. Various structures enter and leave the lung via its root. The root is enclosed in a short tubular sheet of pleura that joins the pulmonary and mediastinal parts of pleura . It extends inferiorly as a narrow fold - The pulmonary ligament.

2023年10月30日 · Structurally, the hilum is a large triangular depressed area on the lung that is located just superior to the center of the mediastinal surface and behind the cardiac impression of each lung, and is found nearer to the back border than to the front.

2025年2月4日 · There are three lung surfaces, each corresponding to an area of the thorax. The mediastinal surface of the lung faces the lateral aspect of the middle mediastinum. The lung hilum (where structures enter and leave the lung) is located on this surface. The base of the lung is formed by the diaphragmatic surface. It rests on the dome of the ...

2020年10月27日 · The hilum of the lung (also called the root of the lung) is formed by the principal bronchi, the central pulmonary arteries and veins, the bronchial nerves and vessels, and the lymphatics, which enter and leave the lung from the mediastinum ( Fig. 1.2). The root of the right lung lies behind the SVC, the superior part of the right atrium, and ...

Innervate the parietal pleura lining the central portion of diaphragm and the mediastinum. The visceral pleura surrounds and is intimately attached to each lung and follows the contour of the lobes; the visceral pleura is contiguous with the parietal pleura at the hilum of each lung (Figure 3-1B–D). Function.

Figure 22.2.1 Gross Anatomy of the Lungs. Each lung is composed of smaller units called lobes. Fissures separate these lobes from each other. The right lung consists of three lobes: the superior, middle, and inferior lobes. The left lung consists of …
