Thoracic cavity Latin cavitas thoracis Gray's subject #136 524 Dorlands/Elsevier Thoracic cavity
The thoracic area includes the tendons as well as the cardiovascular system which could be damaged from injury to the back, spine or the neck.
Structures within the thoracic cavity include:
- structures of the cardiovascular system, including the heart and great vessels, which include the thoracic aorta, the pulmonary artery and all its branches, the superior and inferior vena cava, the pulmonary veins, and the azygos vein
- structures of the respiratory system, including the trachea, bronchi and lungs
- structures of the digestive system, including the esophagus,
- endocrine glands, including the thymus gland,
- structures of the nervous system including the paired vagus nerves, and the paired sympathetic chains,
- lymphatics including the thoracic duct.
It contains three potential spaces lined with mesothelium: the paired pleural cavities and the pericardial cavity. The mediastinum comprises those organs which lie in the centre of the chest between the lungs.
If the pleural cavity is breached from the outside, as by a bullet wound or knife wound, a pneumothorax, or air in the cavity, may result. If the volume of air is significant, one or both lungs may collapse, which requires immediate medical attention.
