After the diaphragm contracts, which direction does it move?

Explanation:
When the diaphragm contracts, it moves downward. This movement occurs because the diaphragm is a dome-shaped muscle located at the base of the thoracic cavity, and when it contracts, it flattens out. This flattening increases the volume of the thoracic cavity, creating a negative pressure that pulls air into the lungs. The downward movement of the diaphragm is a crucial component of the inhalation process, allowing for effective ventilation of the lungs. This is fundamental to understanding how the respiratory system works during the process of gas exchange.
