Question

which muscular partition separates abdonimal cavity and thoracic cavity

Answer 1

The muscular partition between thoracic cavity and abdominal cavity is called the diaphragm, which is known as the primary inspiratory muscle that accounts for greater than 50% of tidal volume. In addition to this, the muscle is shaped like a dome and is located in the inner ribs.

Answer 2

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, a negative vacuum is created which draws air into the lungs.
