Question

if the diaphragm and ribs do not expand and contract what will be the consequence.​

Answer 1

Explanation:

The diaphragm is a muscle crucial for breathing. When the diaphragm contracts, suction is created that draws air into the lungs. Air is exhaled as the diaphragm relaxes, in combination with other muscles and tissues. When the diaphragm is not working properly, respiratory issues may occur

Answer 2

If the diaphragm and ribs do not expand and contract the consequence will be as follows:

• The diaphragm contracts at the time when the lungs inhale and pulls downward. The muscles between the ribs contract and pull upward at the same time.
• The size of the thoracic cavity gets increased due to this and the pressure gets decreased inside. As a result, the lungs are filled as the air rushes in.
• The diaphragm returns to its domelike shape upon exhalation.
