Answer Details
The sheet of muscle that separates the thoracic and abdominal cavities is called the diaphragm. The diaphragm is a thin, dome-shaped muscle that separates the chest cavity (thorax) from the abdominal cavity. It plays an important role in breathing, as it contracts and relaxes to create changes in pressure that help to move air in and out of the lungs. In addition to its role in breathing, the diaphragm also plays a role in the function of several other organs located in the thoracic and abdominal cavities, such as the heart, liver, and spleen. It also helps to maintain the position of the stomach and intestines. Overall, the diaphragm is a vital muscle that is essential for breathing and the proper functioning of several other organs in the body.
