The thoracic cavity contains the heart, lungs, and esophagus. These organs are protected by the rib cage, sternum, and vertebral column.
The heart is in the thoracic cavity in a part called the mediastinum. It is protected by the pericardium, a membranous sac that surround the heart. The mediastinum is that space in the thoracic cavity between the lungs that contains the heart. It also contains the aorta, esophagus, trachea and thymus.The pleural cavity is the space in the chest between the lungs.
this is the thoracic cavity, the space between the neck and the abdomen, this contains the lungs, heart & the main artery called the aorta, the lungs are covered by a membrane called the pleura which holds the lungs in situ and is the area affected by pleurisy, if air or gasses are allowed to permeate this area outside the lungs the vacuum that enables breathing is compromised and a collapsed lung can occur.
It separates the heart and lungs from the abdominal cavity.
The heart is located in the thoracic cavity, which also includes the lungs. In addition, the heart is in the mediastinum, which is the area between the two lungs.
