Mahsulot tavsifi:

The nervous system adjusts the rate of alveolar ventilation to the demands of the body so that the (PO2) and (PCO2) in the arterial blood are hardly altered even during heavy exercise and most types of respiratory stress. The respiratory center is composed of three major collections of neurons: a dorsal respiratory group (DRG), located in the dorsal portion of the medulla (causes Inspiration), a ventral respiratory group (VRG), located in the ventrolateral part of the medulla (causes expiration), and the pontine centers (a-pneumotaxic center, located dorsally in the superior portion of the pons, mainly controls rate and depth of breathing), and b-apneustic center. The DRG of neurons plays the most fundamental role in the control of respiration.
