The diaphragm relaxes during EXHALATION. Your diaphragm flattens when you inhale, creating more space for the lungs to take in more air.

Does exhalation occur when the diaphragm and rib cage muscles relax?
Yes, exhalation occurs when the diaphragm and muscles of the rib cage relax.
When the rib muscles and diaphragm relax and the chest cavity becomes what?
When the diaphragm and muscles of the rib cage relax, the thoracic cavity becomes smaller. These changes occur during exhalation.
What occurs when the respiratory center stops sending nerve signals to the diaphragm and the rib cage?
muscles relax and expiration occurs
What happens to a muscle when it relaxes?
all the muscle filaments move away from each other
What happens to the rib cage when inhaling and exhaling?
it expands as we inhale and contrasts as we exhale...this allows our lungs to fill up with air without pushing on out rib cage the rib cage moves up and out when inhaling and moves down and in when exhaling.
What happens to your diaphragm rib cage and lungs often you exhale?
Your diaphragm expands, your rib cage goes up, and your lungs also expand. I learned this in science.
What muscles do we use to get oxygen into our bodies and carbon dioxide out?
Here is the entire list:Scalenes (Elevate rib cage, assist in inhalation)Sternocleidomastoid (Elevate Rib Cage, assist in inhalation)Pectoralis minor (Elevate Rib Cage, assist in inhalation)External Intercostals (Elevate rib cage, assist in inhalation)Internal Intercostals (Depress, assist in exhalation)Diaphragm (Prime mover of inhalation)When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity.The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
What large muscle located the chest respiration?
There are several muscles involved in breathing:Scalenes (Elevate rib cage, assist in inhalation)Sternocleidomastoid (Elevate Rib Cage, assist in inhalation)Pectoralis minor (Elevate Rib Cage, assist in inhalation)External Intercostals (Elevate rib cage, assist in inhalation)Internal Intercostals (Depress, assist in exhalation)Diaphragm (Prime mover of inhalation)When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity.The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
Why does air enter the lungs upon inhalation?
During inspiration, the alveolar pressure is less than the atmospheric pressure. This causes air to flow into the alveoli. The external intercostal muscles and diaphragm contract during this phase.
Does the axial skeleton assist in respiration?
No really. The muscles that move the rib cage are involved in breathing along with the diaphragm.
Where liver located?
it is located in the upper abdomen to the right of the stomach and immediately below the diaphragm (the diaphragm is a set a muscles below the rib cage and lungs that help with breathing.)
Which of the following respiratory processes requires the active use of muscles?
Inhalation, because the muscles of the rib cage and the diaphragm contract (creating a negative pressure) OBX ;)
