ABSTRACT
The diaphragm is a thin muscle with a full-time job. It is innervated by the ipsilateral phrenic nerve and has an abundant blood supply.1 The anatomical role of the diaphragm consists of dividing the two large cavities of the human body and maintaining its different pressures.2
Its presence separates and contains the viscera of the abdominal and thoracic cavities. The symptoms related to diaphragmatic injuries are caused by the incapacity to contain the abdominal viscera in the cavity favored by the pressure gradient.1
