| Sistema corporal | Muscular | Cardiovascular |
| Região corporal | Thorax | Heart Region |
| Função | The primary muscle of respiration. Contraction flattens the dome-shaped muscle, increasing thoracic volume and creating negative pressure to draw air into the lungs during inspiration. | The central pump of the cardiovascular system, propelling blood through the pulmonary and systemic circuits. Beats approximately 100,000 times per day, pumping about 7,500 liters of blood daily. |
| Significado clínico | Diaphragmatic hernias allow abdominal organs to enter the thoracic cavity. Phrenic nerve paralysis causes diaphragmatic elevation. Hiccups result from involuntary diaphragmatic spasms. | Coronary artery disease is the leading cause of death worldwide. Myocardial infarction results from coronary artery occlusion. Heart failure, valvular diseases, arrhythmias, and congenital heart defects are major cardiovascular conditions. |
