The most important physiological factors for regulating breathing are

The most important physiological factor for regulating breathing is CO? , mainly acting on central chemoreceptors, high concentration of co? It mainly stimulates the central chemoreceptor, that is, the medullary chemoreceptor.

Adjusting breathing can relieve tension through breathing adjustment. Exhale naturally and slowly exhale the air at the bottom of the lungs. At this time, the shoulders, chest and diaphragm feel relaxed and comfortable. When you breathe, you have to imagine that the tension is slowly driven away. Pay attention to the pace and speed of relaxation.

Extended data:

Both Pco2 and H+ are stronger central receptors than peripheral receptors. The central receptor is not sensitive to PO2, so the change of PO2 only works through peripheral receptors. Under normal circumstances, in addition to the cerebral cortex can actively and temporarily change the speed and depth of breathing, there are also respiratory control centers that involuntarily regulate breathing, including two parts, one in the pons and the other in the medulla oblongata.

The respiratory chain structure is destroyed or the decoupling agent is added. This adjustment will be released and cause electron transfer independent of ADP. Respiratory regulation can avoid unnecessary consumption of substrate and oxygen, which is of physiological significance to balance ATP consumption and supply.
