What two cavities make up the Abdominopelvic Cavity?

• A. Cranial and Pelvic
• B. Abdominal and Pelvic
• C. Abdominal and Thoracic
• D. Spinal and Thoracic

Answer: (B)

The main idea here is how the body’s cavities are organized and which spaces together form the abdominopelvic region. The abdominopelvic cavity is the portion of the ventral body cavity located below the diaphragm and is considered as two connected spaces: the abdominal cavity and the pelvic cavity. This combination creates one continuous lower cavity that houses much of the digestive and reproductive organs, among others. The diaphragm marks the upper boundary, and below it, the two compartments are divided conceptually into abdomen and pelvis. The other options don’t fit because they refer to cavities in other regions: the cranial cavity houses the brain, the spinal cavity runs along the spinal column, and the thoracic cavity sits above the diaphragm inside the chest.
