Verified step by step guidance

1. Step 1: Understand the definition of body cavities. Body cavities are spaces within the body that house and protect internal organs. Major body cavities include the dorsal cavity and the ventral cavity.
2. Step 2: Identify the dorsal cavity, which includes the cranial cavity (housing the brain) and the spinal cavity (housing the spinal cord). These cavities protect the central nervous system.
3. Step 3: Recognize the ventral cavity, which is subdivided into the thoracic cavity and the abdominopelvic cavity. The thoracic cavity contains the pleural cavities (each surrounding a lung) and the pericardial cavity (surrounding the heart).
4. Step 4: Note that the pleural cavity specifically contains the lungs, not the heart. The heart is located in the pericardial cavity, which is part of the thoracic cavity but separate from the pleural cavities.
5. Step 5: Confirm that the abdominal cavity contains organs such as the stomach and intestines, which are part of the abdominopelvic cavity.
