Verified step by step guidance

Step 1: Begin by understanding the concept of body cavities. Body cavities are spaces within the body that house and protect internal organs. They are divided into dorsal (posterior) and ventral (anterior) cavities, with further subdivisions.

Step 2: Focus on the ventral cavity, which is divided into the thoracic cavity and the abdominopelvic cavity. The thoracic cavity contains the lungs, heart, and other structures.

Step 3: Within the thoracic cavity, identify the pleural cavities. These are two separate cavities that surround each lung and are lined by the pleura, a serous membrane that reduces friction during breathing.

Step 4: Eliminate the incorrect options: The abdominal cavity houses organs like the stomach and intestines, not the lungs. The cranial cavity contains the brain, and the pericardial cavity surrounds the heart.

Step 5: Conclude that the lungs are located in the pleural cavities, which are part of the thoracic cavity within the ventral body cavity.
