The diaphragm separates the thoracic cavity containing the heart and lungs, from the abdominal cavity and performs an important function in respiration: as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.tructure [edit]. The diaphragm is a dome-shaped structure of muscle and fibrous tissue that separates the thoracic cavity from the abdomen. The dome curves upwards. The superior surface of the dome forms the floor of the thoracic cavity, and the inferior surface the roof of the abdominal cavity.
The diaphragm is a thin layer of muscle and tissue that separates the chest and abdominal cavity. It is the muscle that the body uses to breathe. When your child has a congenital diaphragmatic (CDH), it means that thereâs a hole in that layerâor, rarely, that the diaphragm is missing altogether. The contents of your child's abdomen, including the stomach, intestines, liver and spleen may go through the hole and into his chest.
