1 Oxygen: Specialized nerve cells within the aorta and carotid arteries called peripheral chemoreceptors monitor the oxygen concentration of the blood and feed back on the respiratory centers. 2  If the oxygen concentration in the blood decreases, they tell the respiratory centers to increase the rate and depth of breathing. This mechanism prevents damage to the lungs that would be caused by over-inflation. 2  Signals from higher brain centers: Nerve cells in the hypothalamus and cortex also influence the activity of the respiratory centers. 3  During pain or strong emotions, the hypothalamus will tell the respiratory centers to speed up.
Optimal breathing on the other hand which includes a balance of appropriate endogenous respiration as well as natural breathing reflex development will both enhance and extend calm and recovery.trictly speaking, our red blood cells are the major transport vehicle of O2 into your body. Endogenous breathing (EB) helps to increase blood pressure in the lungs and concentrate the O2 in your red blood cells. Buteyko, one style of Endogenous Breathing training, is an approach to handle asthma.
