Which cavity contains the urinary bladder?

• A. Abdominal body cavity
• B. Thoracic body cavity
• C. Spinal body cavity
• D. Pelvic body cavity

Answer: (D)

Understanding where organs sit inside the major body cavities helps answer this. The urinary bladder is housed in the pelvic cavity, the space bounded by the pelvic bones in the lower part of the torso. It stores urine and is positioned with other pelvic organs nearby. The abdominal cavity, by contrast, contains digestive organs like the stomach and intestines; the thoracic cavity contains the heart and lungs; and the spinal cavity runs along the back to protect the spinal cord. So, the pelvic cavity is the correct location for the bladder (though a full bladder can extend a bit into the lower abdomen, its primary location is in the pelvis).
