Functions of carbon dioxide
CO2 it is the main regulator of vascular tone in humans. Exerting influence on the vasomotor center in the medulla oblongata, it gives a signal to the vessels vasoconstriction or vasodilation, depending on the conditions required for an adequate adaptation of the organism. The level of carbon dioxide affects not only the pressure readings, blood supply to organs and tissues, but also on the rate and depth of breathing humoral transfer of O2 and nutrients to the cells and is an essential element of cell respiration, to maintain the
acid-base balance, ie, the main bicarbonate buffer component system of the human body, and many other factors.
