The root of the lung is a group of structures that emerge at the hilum of each lung, just above the middle of the mediastinal surface and behind the cardiac impression of the lung. It is nearer to the back (posterior border) than the front (anterior border). The root of the lung is connected by the structures that form it to the heart and the ...
A heart attack is a potentially life-threatening medical emergency that can lead to cardiac arrest or death. Heart attacks are common, too, with an estimated 805,000 people in the United States ...
The cardiac impression is an indentation formed on the surfaces of the lungs where they rest against the heart. Both lungs have a central recession called the hilum, where the blood vessels and airways pass into the lungs making up the root of the lung. [4] There are also bronchopulmonary lymph nodes on the hilum. [3]
Mediastinal shift is an abnormal movement of the mediastinal structures toward one side of the chest cavity. A shift indicates a severe imbalance of pressures inside the chest. [ 1 ] Mediastinal shifts are generally caused by increased lung volume, decreased lung volume, or abnormalities in the pleural space.
This is a type of heart valve disease in which the pulmonary artery, the vessel connecting the heart to the lungs, is too narrow or thick. Atrial septal defect. An atrial septal defect is a hole ...
Common warning signs of a heart attack are discomfort or pain in the chest; discomfort in other areas of the upper body, including pain in in one or both arms, the back, neck, jaw or stomach; and ...
Bronchopulmonary nodes (hilar nodes) situate in the hilum of each lung. Pulmonary nodes are embedded the lung substance on the larger branches of the bronchi. The afferents of the tracheobronchial glands drain the lungs and bronchi, the thoracic part of the trachea and the heart ; some of the efferents of the posterior mediastinal glands also ...
Pulmonary heart disease, also known as cor pulmonale, is the enlargement and failure of the right ventricle of the heart as a response to increased vascular resistance (such as from pulmonic stenosis) or high blood pressure in the lungs. [2] Chronic pulmonary heart disease usually results in right ventricular hypertrophy (RVH), [4] whereas ...
