प्रश्न
Explain with reasons.
Upward and downward movement of diaphragm occurs consecutively.
उत्तर
The diaphragm is a muscular partition which is present between the thoracic cavity and the abdominal cavity. During the process of breathing, the upward and downward movement of the diaphragm occurs simultaneously. When we inhale, the ribs rise up while the diaphragm lowers down simultaneously causing a decrease in pressure on the lungs. This results in the moving of air into the lungs through the nose. As the ribs return to their original position, the diaphragm rises up leading to the increase in pressure inside the lungs. This results in moving of the air outside the nose.
