Get a handful labeled lung diagrams to assist your study about human’s lung anatomy. These 101 Diagramss are designed to guide you in studying the structure of the lung. As one of the main organ in the respiratory system, the lungs are a pair of organs in the chest that are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. The function of the lungs is to oxygenate blood by bringing inspired air into close contact with oxygen-poor blood in the pulmonary capillaries. Follow the following diagrams to know more about the anatomy of the lungs!
As you can see in the lung diagram above, the human lungs are a pair of large, spongy organs optimized for gas exchange between our blood and the air. 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 two lobes: the superior and inferior lobes. The details of each lung are on the following lung diagrams.
The right lung has both more lobes and segments than the left. It is divided into three lobes, an upper, middle, and a lower, by two fissures, one oblique and one horizontal. The left lung is divided into two lobes, an upper and a lower, by the oblique fissure, which extends from the costal to the mediastinal surface of the lung both above and below the hilum. Each lung is enclosed within a cavity that is surrounded by the pleura. The right and left pleurae, which enclose the right and left lungs, respectively, are separated by the mediastinum. The pleurae consist of two layers: visceral and parietal pleura.
