Final answer:
The two primary cavities within the ventral cavity are the thoracic and abdominopelvic cavities. The thoracic cavity contains the organs of the chest, while the abdominopelvic cavity is divided into the abdominal and pelvic cavities.
Step-by-step explanation:
The two primary cavities within the ventral cavity are the thoracic and abdominopelvic cavities.
In the ventral cavity, the thoracic cavity is located above the diaphragm and contains the organs of the chest, such as the heart and lungs.
The abdominopelvic cavity is located below the diaphragm and is further divided into the abdominal cavity, which contains organs such as the liver and stomach, and the pelvic cavity, which contains reproductive organs.
