The regulation of breathing is controlled by the neurons in the medulla. Under most conditions, breathing rate is maintained involuntarily by the medulla. This system is very flexible and it is possible for breathing rate to be controlled voluntarily. Breathing is accomplished by the medulla firing action potentials at a rhythmical rate. These action potentials cause the muscles in the diaphragm and theintercostal muscles to contract. The rate and depth of breathing is dependent upon the medulla's ability to detect pH levels in the blood. By detecting changes in pH, the medulla is indirectly determining the amount of carbon dioxide in the blood. The following reaction demonstrates the relationship between carbon dioxide levels and pH.
CO2 + H2O <=> H2CO3 <=> (H+) + (HCO-)
At low pH levels (high [H+]), the respiratory center in the medulla becomes stimulated and results in an increase in the rate and depth of breathing. However when pH is high, breathing becomes slower and shallower due to a decrease in nervous stimulation. For instance in hyperventilation pH levels are so high that there is a temporary cessation of breathing (apnea).
you breathing is out and in and that is the breathing is changes is

The brain stem is the part that controls breathing, it is the stem that allows the respiratory system to work and help you breathe
Pituitary, right? That's supposed to be the "Master Gland".
The diaphragm contractions are primarily regulated by the phrenic nerve, which originates from the cervical spine (C3-C5). This nerve controls the contraction and relaxation of the diaphragm muscle, allowing for the process of breathing to occur efficiently.
Yes, breathing is primarily regulated by the levels of carbon dioxide in the blood. When carbon dioxide levels rise, the body signals the need to breathe more to expel excess carbon dioxide and take in fresh oxygen. Conversely, if carbon dioxide levels drop too low, breathing may decrease to retain carbon dioxide.
No, breathing is not voluntary. We breathe because we need to and we don't think about it. If we didn't breathe we would be dead, so it is an involuntary action. Breathing is unique in that you can temporarily control it, but most of the time breathing happens without thinking.
Yes, its like the heart beat it's always beating because of the involuntary muscles When you sleep the involuntary muscles make you breath
Breathing involves the contraction of the diaphragm and intercostal muscles to create a pressure difference in the chest cavity, causing air to rush into the lungs (inspiration) or be expelled from the lungs (expiration). This process is regulated by the brainstem, which controls the rate and depth of breathing based on signals from chemoreceptors sensing oxygen and carbon dioxide levels in the blood.
When reading aloud, the breathing cycle may become more regulated and intentional. This can involve taking deeper breaths to support consistent voice projection and pausing to replenish air while speaking. Additionally, individuals may adjust their breathing pattern to ensure smooth delivery of sentences and phrases.
