Which of the following organ systems—digestive, respiratory, reproductive, circulatory, urinary, or muscular—are found in both subdivisions of the ventral body cavity?

digestive, circulatory, and muscular.

Explanation:

There are two main cavities in the human body. They are: dorsal cavity of the body and ventral cavity of the body. The first is formed by the bones of the skull, where we find the brain; and also through the vertebral canal (spine + spinal cord). The second is located in the belly region and is subdivided by the diaphragm into the thoracic and abdominopelvic cavities (where the viscera are). In the central cavity, several organs and systems can be found, but among the above options, we can say that the digestive, circulatory and muscular systems are found in the ventral cavity.
