Which cavity is specifically associated with the lungs?

The thoracic cavity is specifically associated with the lungs as it encompasses the area within the rib cage that houses not only the lungs but also the heart and major blood vessels. It is divided from the abdominal cavity by the diaphragm, which aids in respiration. The thoracic cavity is crucial for the function of the respiratory system, as it provides the necessary environment for the lungs to expand and contract during inhalation and exhalation. The pleural membranes lining the thoracic cavity also facilitate the movement of the lungs within this space.

In contrast, the pelvic cavity is primarily associated with the reproductive organs and lower digestive tract, the cranial cavity contains the brain, and the abdominal cavity houses various organs such as the stomach, liver, and intestines. Thus, the correct association of the thoracic cavity with the lungs highlights its vital role in respiratory functions and the anatomical organization of the body.
