What happen to diaphragm when we inhale whe we exhale?

When we inhale, the diaphragm contracts and moves downward, increasing the volume of the thoracic cavity and allowing air to flow into the lungs. During exhalation, the diaphragm relaxes and moves upward, reducing the thoracic cavity's volume and pushing air out of the lungs. This rhythmic movement of the diaphragm is essential for efficient breathing.
