Quizplus · Accepted Answer

The diaphragm is a thin, dome-shaped muscle that separates the thoracic cavity from the abdominal cavity. It attaches to the bottom of the rib cage and plays a key role in respiration, helping to draw air into the lungs. The rib cage and peritoneum are not responsible for separating the two cavities. The perineum is located in the pelvic region and is not involved in the separation of the thoracic and abdominal cavities.
