Students have asked these similar questions
which respiratory muscle is responsible for moving the majority of air during eupnea? sternocleidomastoid, intercostals, or diaphragm.
Jackie is a professional singer. Her singing tasks require her to allocate only
1 second for inhalation and longer expiration for prolonged notes while
performing. Hence, there is a need to elevate intra-abdominal pressure to
improve control during long utterances. All these muscles are affected in
this activity. SELECT ALL THAT APPLY. *
Rectus abdominis
V Diaphragm
Intercostal muscles
External oblique
Which respiratory center/s is/ are used by Jackie (from previous item) for
elevating the intra- abdominal pressure?*
Dorsal respiratory group
Ventral respiratory group
Pontine respiratory group

The action of the diaphragm and intercostal muscles
The diagram below shows inhalation and exhalation.
Complete the following sentences to explain how we breathe in.
The intercostal muscles between the _______________
This moves the ribs _______________ and _______________.
At the same time, the diaphragm muscle _______________ and moves _______________.
The volume of air inside the chest _______________.
This decreases the pressure inside the chest. The air pressure outside the chest is higher so air enters the lungs.
Complete the following sentences to explain how we breathe out.
The intercostal muscles _______________.
The ribs are moved _______________ and _______________.
At the same time, the diaphragm muscle _______________ and moves _______________.
The volume of air inside the chest __________________.
This increases the pressure inside the chest. The air pressure outside the chest is now lower so air leaves the lungs.
