The diaphragm is a thin, dome-shaped muscular structure that separates the chest cavity from the abdominal cavity. It consists of two main parts: the central section is composed of smooth muscle, while the peripheral section is made up of striated muscle fibers. Numerous openings in the diaphragm allow essential vessels, nerves, and the esophagus to pass through.
The primary function of the diaphragm is to facilitate breathing. When the diaphragm contracts, the chest cavity’s volume increases, reducing pressure in the lungs and enabling air to flow in. Additionally, the diaphragm plays a significant role in coughing, vomiting, sound production, and maintaining stable blood pressure by ensuring oxygen supply to the heart and other organs.
Any dysfunction of the diaphragm, such as a diaphragmatic hernia, can have serious consequences for overall health. This condition occurs when abdominal organs shift into the chest cavity, potentially leading to chronic respiratory issues. Diaphragmatic hernias can be congenital or acquired, with symptoms varying depending on the severity of the condition.
