WebSep 19, 2024 · Carbon dioxide (CO2) is the major waste product of aerobic respiration. Too much or too little CO2 in the blood can lead to serious consequences. ... The main role of CO 2 is to regulate the pH of the blood – this is much more important that transporting CO 2 to the lungs for exhalation. By TeachMeSeries Ltd (2024) Fig 1 – The reaction that ... WebJun 21, 2024 · Carbon dioxide plays a remarkable role in the human body mainly through pH regulation of the blood. The pH is the primary stimulus to initiate ventilation. In its normal state, the body maintains CO2 in a well-controlled range from 38 to 42 mm Hg by balancing its production and elimination.

WebThe lungs help to regulate blood pH by controlling the concentration of carbon dioxide (CO2) in the blood. When CO2 combines with water in the blood, it forms carbonic acid, which dissociates into H+ ions and bicarbonate (HCO3-) ions. ... The blood pH will be within the normal range if the ratio of 20 to 1 is maintained between bicarbonate and ... WebRebreathing exhaled air will rapidly bring blood pH down toward normal. The chemical reactions that regulate the levels of CO 2 and carbonic acid occur in the lungs when blood travels through the lung’s pulmonary capillaries. … sharon hyde green bay wis
