Explain the mechanism of ventilation in human lungs (you should talk about the diaphragm, abdominal muscles and rib cage and intercostal muscles)

When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs. Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity.
