Transport of Carbon Dioxide in the Blood
Carbon dioxide (CO2) is the major waste product of aerobic respiration.
Transport of carbon dioxide in blood pdf
Too much or too little CO2 in the blood can lead to serious consequences. This article will consider CO2 transport in the blood, its role in maintaining blood pH and conclude by discussing its clinical relevance.
Carbon Dioxide in the Blood
The main role of CO2 is to regulate the pH of the blood – this is much more important that transporting CO2 to the lungs for exhalation.
Figure 1 shows how CO2 dissolves in the blood.
The conversion of carbonic acid (H2CO3) to a hydrogen and bicarbonate ion (H+ + HCO3-) is almost instantaneous. A small amount of dissolved CO2 produces a small rise in hydrogen ions which is capable of altering the blood pH.
The proportion of CO2 to HCO3- is critical and explains why this occurs.
This ratio is roughly 1:20, therefore a rise of 1 CO2 requires
