Verified step by step guidance1
Begin by understanding the concept of body cavities. Body cavities are spaces within the body that contain vital organs. They are divided into dorsal and ventral cavities.
The dorsal cavity includes the cranial cavity, which houses the brain, and the spinal cavity, which contains the spinal cord. These are not further divided into other cavities.
The ventral cavity is larger and includes the thoracic cavity and the abdominopelvic cavity. The thoracic cavity is further divided into smaller cavities.
Within the thoracic cavity, there are the pleural cavities, which surround each lung, and the pericardial cavity, which encloses the heart. Additionally, the mediastinum is a central compartment within the thoracic cavity.
The abdominopelvic cavity is divided into the abdominal cavity and the pelvic cavity, but these are not further subdivided into smaller cavities like the thoracic cavity.
