False. When nerve impulses pass to the diaphragm, it contracts, which expands the chest cavity and allows air to enter the lungs (inhalation). The diaphragm relaxes during exhalation, allowing air to be pushed out of the lungs.
The dipahragm is innervated by the phrenic nerve. This nerve responds to the stimulus sent by the a very particular set of neurons located in the medulla. The main ones are called VRG and DRG. Of these the VRG sends signals to the diaphragm to contract, when the signal is not "on" then the diaphragm relaxes. DRG modulates the depth of breath. There is another group called the pneumotaxic center found in the ponds; this group keeps the VRG in check. If the frequency of respiration becomes too great the pneumotaxic center inhibits depolarization of the VRG for a while in an attempt to restore a "normal" breathing pattern
during the exhalation phase, the diaphragm relaxes, that is resuming its dome shaped position. The intercostal muscle likewise relax and the rib cage moves down deflate . ACHECHE from:Alkenneth Angelico O. Alderite
Yes, speaking involves the use of the diaphragm along with other muscles in the chest, throat, and mouth. The diaphragm contracts and relaxes to help control the flow of air from the lungs, which is necessary for producing sound during speech.
Breathing is done by your diaphragm. When you breathe in, your diaphragm tightens (contracts) and moves downward so your lungs can expand. When you breathe out (exhale) your diaphragm relaxes (expands) and moves up into your chest.
The diaphragm relaxes to help squeeze the air out of your lungs. When the diaphragm contracts, it flattens and pulls air into your lungs. When it relaxes into its dome-shaped position, air is pushed out.
During exhalation the diaphragm relaxes and the chest cavity gets smaller.
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.
Your diaphragm contracts and expands when you breath. When the diaphragm contracts, air rushes into the lungs. When the diaphragm relaxes, air is exhaled.
It is called your diaphragm.
Diaphragm
When the Diaphragm contracts, it is pulled down, and is pulled back up when it relaxes.Also, when you inhale, it contracts. When you exhale, it relaxes.
False. When nerve impulses pass to the diaphragm, it contracts, which expands the chest cavity and allows air to enter the lungs (inhalation). The diaphragm relaxes during exhalation, allowing air to be pushed out of the lungs.
Lungs do not contain muscle tissue. air enters your lungs when the muscular diaphragm contracts, pulling your ribs up and out. The diaphragm relaxes when you exhale.
The diaphragm relaxes and reduces the space in the chest cavity.
The Diaphragm.
Your lungs deflate nad you breathe out
