How does the diaphragm can be forced to move higher than normal by contraction of what muscles?
The abdominal muscles squeeze abdominal organs inwards increasing the pressure in the abdominal cavity, thus forcing the diaphragm closer to the lungs.
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.
Why does your stomach move while you breath?
cause your diaphragm expands
When you inhale what direction does the diaphragm move?
Upwards, toward the head.
Function of the diaphragm?
to move when the lungs expand so the lungs dont get crushed
What muscle compress and move downward when you inhale?
the diaphragm. It is right above the heart and lungs, and expands and contracts when you breathe in and out. You can almost feel it move down a little, when you release air.
What happens if you have move your diaphragm from falling over?
nothing
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 happens to your ribs when you inhaled?
they expand, or get biggerThe contraction of your intercostal muscles causes the rib cage to move up and out, thus increasing the volume of the thoracic cavity, decreasing the pressure, so air is forced in.If you're asking for GCSE, the term you need to use is the "ribs move up and out". Don't forget the contraction of the diaphragm, as it flattens it aids the increase in volume of the thoracic cavity.
What happens to the diaphragm when a person inhales?
The diafragm moves downward and the intercostal muscles contract pushing the chest outward and upward causing negative pressure in the lung structure - air will allways move from a high pressure area to a low pressure area, hence, into the lungs.
What enables us to breathe?
The contraction of the diaphragm causes it to move down, increasing the volume of the thoracic cavity. This movement and volume change decrease the pressure in the lungs, and air rushes in.
How do star fish move about?
the fish moves like a bird in air.Its limbs swing like that of a bird. The body acts like a diaphragm by moving upward and downward to reduce the weight
What stimulates the diaphragm?
The diaphragm is stimulated to contract and relax by the phrenic nerve, which originates from the cervical spine. This nerve sends signals to the diaphragm to contract, allowing it to move downward and create negative pressure in the chest cavity for inhalation, and then to relax for exhalation.
What are you doing when your diaphragm moves up and your ribs move down and in?
Your diaphragm lowers and your ribs expand outwards
What muscles move the air in and out of the lungs?
I think you meant move air into the lungs. The muscle is the diaphragm.
