How does the respiratory system expand and contract?
Thoracic muscles & the diaphragm change the shape of the chest.
What causes the respiratory system to work?
the diaphragm and specialized muscles
What muscle contract during inhalation and what muscles contract during exhalation?
The intercostal muscles, (muscles between the ribs), contract.
During eupnea, which muscles contract to facilitate expiration?
During eupnea, the diaphragm and external intercostal muscles contract to facilitate expiration.
How air exhaled?
The muscles in your diaphragm contract to push the air out of your lungs.
Rib muscles and diaphragm contract making the chest cavity?
Increases
Why does the respiratory muscles increase in strength?

How does the diaphragm and rib muscles work together to control inhaling and exhaling?
When you breathe, the actions of your rib muscles and diaphragm expand or contract your chest. As a result, air flows in and out.
Is a skeletal muscle a voluntary muscle?
Almost all skeletal muscles are voluntary. But respiratory muscles, diaphragm and intercostal, are not completely voluntary.
What does the rib muscles and diaphragm contract do to the chest cavity?
The space in your chest cavity increases.
How are diaphragm and intercostal muscles stimulated?
The diaphragm is stimulated the same way all other muscles are - nerve impulses that originate in the brain (or sometimes the spinal cord). The intercostal muscles expand during inhalation and contract during exhalation in response to the movement of the lungs by the diaphragm.
