When the diaphragm relaxes it moves upward. This causes the ribs to move inward and downward and makes the chest cavity smaller. Air is forced out the lungs as you?

What causes overactive diaphragm?
Hiccups
What is downward displacement of air?
Downward displacement of air happens when you fill the upper part of a pressure chamber with steam. This causes the denser air below to move downward.
How does the diaphragm do in the respiratory system?
The diaphragm is shaped like a mushroom and is indirectly connected to the lungs by the vacuum that exists in the intervening membranes. (This is why a punctured lung is so very bad and painful.) The outer edges of the mushroom shaped diaphragm are attached to the lower edges of the ribs. This is why rib stability is important in the vocal process. The stem of the mushroom is the active muscle. The impulse from the brain causes the muscle to contract and the connecting vacuum to draw the lungs downward, thus inflating them. (Note the importance of that rib attachment.) After the inhalation is complete, the muscle stem relaxes and like a tennis ball that has been indented, the diaphragm and lungs automatically rebound to their "at rest" position, thus emptying the lungs. The vocal process controls this rebound rate. This is caused by having the stomach muscles balance against the stem muscle when it should be in its relaxed condition and automatically rebounding. (Once again underlining the need for a stable rib foundation.)
What is the definition of diaphragm?
A diaphragm is a thin sheet which separates two volumes or spaces (from Greek for barricade). They are manufactured for a variety of uses; in microphones and earpieces, pumps, and barriers to the passage of sperm for contraception. Many exist in living things, the eardrum being a small but important one. All the above mentioned things would be called a diaphragm. The diaphragm is one particular kind; it is a muscle that is located under the lungs that contracts to let air into the lungs. When the diaphragm "moves down" it causes you to inhale and when your diaphragm relaxes to form a dome shape muscle you exhale. If we didn't have a diaphragm then we wouldn't be able to give birth. The diaphragm also makes us have hiccups! When the regular rhythmic contraction gets disturbed we appear to end up with hiccups.
The Nerve plexus that supplies the diaphragm and thus causes respiratory damage is the plexus?
It is the Cervical Plexus
What happens to cause air to be exhaled from from the lungs?
the diaphragm relaxes and that causes the ribcage to compress (get smaller) this pushes air out, and you have exhailed
Which muscle is under the lungs?
The diaphragm. When it contracts, it increases the space in the chest cavity, and also lowers the pressure inside it. This causes air to be sucked into the lungs. Likewise, when it relaxes, the spaces becomes smaller, and the pressure increases and forces the air out.
Can you really get a sore torso just from laughing?
yes, because when you laugh your diaphragm contracts and relaxes causing stress and in turn causes soreness.
What causes the diaphragm to return to its dome shaped position?
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 muscle contracts to cause a hiccup?
A hiccup is the movement of the diaphragm. The diaphragm is in the thoracic cavity just under the lungs. This organ helps to squeeze the lungs when you exhale in order to get all the air out of the lungs. Holding your breath causes the diaphragm to move downward and stop this movement.

What causes air to enter the lungs?
The diaphragm, below the lungs, contracts causing a lower pressure in the lungs, and pulls the air in. To exhale, the diaphragm relaxes, and the chest muscles contract, forcing the lungs to be smaller and the air to be pushed out. While having sex, this happens faster as we need more energy. ah! ah! ah! oh! oh!oh!
What happens to the diphgram when you inhale?
The diaphragm is a convex shaped muscle (convex side within the chest cavity).When the diaphragm muscle contracts it flattens out and drops down out of the chest cavity making more room and creating a vacuum -- air then rushes into the lungs.When the diaphragm relaxes it moves back up into the chest cavity and expels the air on the lungs. During inhalation, the increased volume of the lungs causes the ribcage to expand. Inhalation - Diaphragm CONTRACTS and moves DOWN (to allow more space in the chest cavity for lungs to expand).Exhalation - Diaphragm RELAXES and moves UP (to force air out of the lungs).
What does the diaphran do to the respiratory system?
The diaphragm is a large, flat muscle located just below your lungs. When it dishes downward, it cause air to be sucked into the lungs. When it dishes upward, it pushes air out of the lungs. In other words, the diaphragm causes you to breath.
What happen to your diaphragm that causes you hiccup?
The diaphragm causes hiccups, what happens is when you eat too fast or eat too much or stomach aches etc.The diaphragm gets annoyed sometimes so it BURSTS up and suddenly hits the voice box and HIC. What happens to the diaphragm is it'll stay a bit sore for a while it depends how the hiccups end so for eg: 5 mins later and the hiccups ended that is because the diaphragm has recovered from the irritation.
What force causes object to move downward?
The force that causes objects to move downward is gravity
What causes air to move into and out of a person lungs?
your diafram
What causes air to enter and leave the lungs?
The air inside our lungs moves in and out because of the movement of the diaphragm as well as the ribs and chest cavity. When we breath in our ribs push out and our diaphragm contracts to create a larger cavity inside your lungs. This causes an area of low pressure which therefore forces air down our trachea into our lungs. When we breath out the opposite happens (diaphragm relaxes and ribs pull in) which creates a smaller cavity in our lungs what therefore forces the air out of our lungs once respiration has taken place. It should be noted that during inspiration as the intercostal muscles expand the rib cage and the diaphragm (more important for volume change) moves inferiorly, this creates negative pressure in the thoracic cavity relative to the atmospheric pressure.. consequently due to the pressure gradient, air can move into the lungs via the trachea. The negative pressure that is caused here is the main propellent of air. Whereas expiration, when the diaphragm and intercostal muscles return to resting position, thus restoring pressure to its normal levels is a passive process. The pressure gradient returns to normal and air can be expired. The importance of the negative pressure created by the intrapleural cavity cannot be stressed enough.
