THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Thoracic Cavity: The ventral body chamber that contains the pericardial cavity (the heart) and the pleural cavity (the lungs).

Detailed explanation-2: -The thoracic cavity is divided by the mediastinum. The heart is in the mediastinum, enclosed by the pericardium. The lungs occupy the left-right regions and the pleura lines the corresponding half of the thorax and forms the lateral mediastinal boundary.

Detailed explanation-3: -Within the thoracic cavity, the lungs are separated from the thoracic wall by the visceral and parietal pleurae. Between these two layers exists a potential space called the pleural cavity. It is clinically significant, as pathologic processes can result in fluid accumulations within this space.

Detailed explanation-4: -The thoracic cavity can typically be divided into well-established compartments. [2] Primarily the pleural cavities and the mediastinum. There are two pleural cavities which respectively contain the left and right lungs and pleura. The mediastinum is central and found between the two bilateral pleural cavities.
