Which of the following consists of the thoracic cavity and the abdominopelvic cavity?

The thoracic cavity and the abdominopelvic cavity are both part of the ventral cavity. The ventral cavity is located on the front side of the body and is subdivided into these two main areas. The thoracic cavity is situated above the diaphragm and contains structures such as the heart and lungs, while the abdominopelvic cavity is located below the diaphragm and holds organs of the digestive and reproductive systems.

This distinction is important in anatomy as it helps in understanding the organization of body structures and their functions. The other cavities mentioned—dorsal, spinal, and cranial—do not encompass both the thoracic and abdominopelvic regions. The dorsal cavity, for instance, includes the cranial cavity and the spinal cavity but is located at the back of the body. Therefore, identifying the ventral cavity as the area containing both the thoracic and abdominopelvic cavities is crucial for grasping human anatomy and its physiological concepts.
