Verified step by step guidance

Understand the concept of body cavities: Body cavities are spaces within the body that house and protect internal organs. The thoracic cavity is divided into smaller cavities, including the pleural cavities, pericardial cavity, and mediastinum.

Identify the pleural cavities: The pleural cavities are two separate spaces within the thoracic cavity, each surrounding one lung. They are lined by the pleura, a serous membrane that reduces friction during breathing.

Differentiate the pericardial cavity: The pericardial cavity is located within the thoracic cavity but surrounds the heart, not the lungs. It is lined by the pericardium, another serous membrane.

Clarify the mediastinum: The mediastinum is the central compartment of the thoracic cavity, located between the pleural cavities. It contains the heart, thymus, esophagus, trachea, and major blood vessels, but does not surround the lungs.

Exclude the abdominal cavity: The abdominal cavity is located below the thoracic cavity and houses organs such as the stomach, liver, and intestines. It is not related to the lungs.
