Which cavity houses urinary bladder, reproductive organs, and rectum?

• A. Abdominal Cavity
• B. Thoracic Cavity
• C. Pelvic Cavity
• D. Pericardial Cavity

Answer: (C)

The main idea is knowing which organs sit in which body cavity. The pelvic cavity is the lower, bony‑lined space within the pelvis. It houses the urinary bladder, the reproductive organs, and the rectum. The bladder sits in this region for most of its size, and the reproductive organs (uterus and ovaries in females; prostate and parts of the reproductive tract in males) occupy this same space. The rectum lies toward the back of the pelvic cavity as it continues down to the anal canal. In contrast, the abdominal cavity contains most of the digestive organs like the stomach and intestines, while the thoracic cavity holds the heart and lungs, with the pericardial cavity surrounding the heart. So, the pelvic cavity best fits the organs listed.
