What is a human diaphragm?
Human bodyScience
Quick Answer
The diaphragm is a large dome-shaped muscle beneath the lungs that plays the main role in breathing. When it contracts, the chest cavity expands and air is drawn into the lungs.
The Full Story
The diaphragm separates the chest cavity from the abdomen and is essential to normal respiration. During inhalation, it flattens downward, increasing the space inside the chest and lowering pressure so air flows into the lungs. When it relaxes, air is pushed out more easily during exhalation. The diaphragm also helps with coughing, sneezing, vomiting, and other pressure-based body functions.
