Parts of Lung
apex base costal surface anterior border cardiac notch mediastinal surface hilum root of the lung posterior border |
apex
base – sits on the diaphragm costal surface –corresponds to the concave thoracic wall anterior border cardiac notch – left lung mediastinal surface – molded to the pericardium and other mediastinal structures hilum – depression located at about the center of the mediastinal surface where the structures that form the root of the lung enter and leave root of the lung – bronchi, pulmonary artery, pulmonary veins, bronchial vessels, nerves, and lymphatics posterior border |

Blood Supply
Arteries |
bronchial arteries – from the thoracic aorta supply the structures comprising the root of the lung, supporting tissues of the lung, and the visceral pleura
