What does the diapragm do for the respiratory?

The diaphragm is a dome-shaped muscle located beneath the lungs that plays a crucial role in respiration. When it contracts, it flattens and moves downward, increasing the volume of the thoracic cavity and allowing air to be drawn into the lungs (inhalation). Conversely, when the diaphragm relaxes, it moves upward, reducing the volume of the thoracic cavity and helping to expel air from the lungs (exhalation). This rhythmic contraction and relaxation are essential for normal breathing.
