Verified step by step guidance

Begin by identifying the two cavities mentioned: the thoracic cavity and the abdominopelvic cavity. The thoracic cavity houses organs such as the lungs and heart, while the abdominopelvic cavity contains organs like the stomach, liver, and intestines.

Understand the role of the diaphragm in the human body. The diaphragm is a dome-shaped muscle that plays a crucial role in respiration by contracting and relaxing to allow air into the lungs.

Recognize that the diaphragm serves as a physical barrier between the thoracic cavity and the abdominopelvic cavity. It separates these two cavities anatomically.

Consider the other structures listed: Mediastinum, Peritoneum, and Pleura. The mediastinum is a central compartment within the thoracic cavity, the peritoneum is a membrane lining the abdominal cavity, and the pleura is a membrane surrounding the lungs.

Conclude that the diaphragm is the correct structure that separates the thoracic cavity from the abdominopelvic cavity, based on its anatomical position and function.
