Why do you switch from breathing into your stomach to your chest?
Stomach breathing is not actually breathing into your stomach. It is breathing as a result of activating your diaphragm - which sits just above your stomach and pushes on your stomach when its pulling air. Diaphragm breathing is deeper breathing and it's where you pull more air into your lungs. Once the deeper parts of your lungs are filled, the air fills the upper part of your lungs in your chest...
What part of breathing is active or requires energy?
Negative Pressure System or to call it simply, Inhalation, is the part of breathing that requires energy. Energy is required for the diaphragm to contract. The diaphragm contracts and moves down, the chest expands, volume of the thoracic cavity and lungs increase. These combined action causes the pressure inside the lung to decrease below that of the atmosphere. As a result, air is pulled into the lungs.
An increase in the amount of carbon dioxide in the blood stimulates the respirayory center in the brainas a result a message is sent from the brain to the?
The increase amount of carbon dioxide in the blood stimulates is called the autonomic nervous system. This is what controls breathing.
Why do pregnant women experience difficult in breathing?
At about nine months a human baby(fetus) has the impulse to push with its legs. This is a natural condition to assist in childbirth. Newborns have the ability to stand with assistance - this is just the residue of this reflex. So sometime, when getting ready to be born, an unborn baby will stiffen its legs. The result of this is a kick in the mother's bladder or in her diaphragm. As the diaphragm is what's responsible for breathing - the process suffers an obstruction.
Is the pressure of contained neon gas increases as more gas is added to the container a chemical change?
Increased pressure is a physical change, not a chemical change - even if the increase in pressure is itself the result of a chemical process.
What effect does the depression of the diaphragm and the expansion of the rip cage and its pressure inside the lungs?
When the diaphragm depresses and the rib cage expands, it increase the volume of the chest cavity. Actually, the rib cage doesn't really expand. The sternum (breastbone) move up and out slightly, moving the ribs slightly with it. This creates a pressure gradient where there is very low pressure in the lungs and higher pressure out. As a result of this gradient, air is almost sucked into the lungs, like air filling a vacuum space. As the diaphragm contracts and gravity pulls the ribs and sternum back down, the air is forced out of the lungs.
What can change the shape of a volcano?
Weathering, erosion, or application of heat or pressure would result in the change in shape of a rock.
Does a nuclear change result from a chemical reaction?
Nope. (Well, the chemical reaction of the high explosives in an A- or H-bomb warhead result in high pressure that then results in a nuclear change (BOOM), but that's a side-effect, not a direct result of the chemical change.)
Does the temperature change cloud formations?
how can changes in temperature and /or air pressure result in the formation of clouds

How are hiccups defined?
result of an involuntary, spasmodic contraction of the diaphragm followed by the closing of
How would a sedimentary rock change to a metamorphic rock?
Through metamorphism, as a result of increase in pressure and/or temperature.
