Which body cavity contains the heart, lungs, and esophagus?

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

Answer: (A)

The chest cavity, or thoracic cavity, is where the heart and lungs reside. The esophagus also runs through this region as it moves from the throat down toward the stomach, passing through the mediastinum inside the thorax. The cranial cavity houses the brain, the abdominal cavity contains organs like the stomach and intestines, and the spinal (vertebral) cavity contains the spinal cord. So the heart, lungs, and esophagus are all located in the thoracic cavity.
