Which of the following cavities is part of the ventral cavity?

The ventral cavity is one of the main body cavities and can be divided into several parts, primarily encompassing the thoracic, abdominal, and pelvic cavities.

The thoracic cavity houses vital organs such as the heart and lungs, while the abdominal cavity contains organs related to digestion and metabolism, such as the stomach and intestines. The pelvic cavity, located beneath the abdominal cavity, contains the reproductive organs, bladder, and rectum. Together, these three cavities are interrelated and form the overall ventral cavity of the body.

In contrast, the cranial cavity is part of the dorsal cavity, housing the brain, and the spinal cavity, which surrounds the spinal cord, is also considered part of the dorsal cavity. Therefore, options that include the cranial or spinal cavities do not fit within the definition of the ventral cavity, making the option that lists thoracic, abdominal, and pelvic cavities the only accurate representation of the ventral cavity's components.
