Solution
- Generally, Carbon dioxide is removed from tissues by blood and released into the air via the lungs.
- Most of the carbon dioxide combines with water and is carried in the plasma as bicarbonate ions.
- If a person holds his breath or undergoing heavy exercise he will produce excess carbon di oxide.
- This excess of carbon dioxide quickly shifts the blood pH to being more acidic.
- Chemoreceptors in the brain and major blood vessels immediately stimulate the breathing center of the brain - the medulla oblongata.
- Hence, as CO2 levels build up and the blood becomes more acidic, we involuntarily breathe faster. This will immediately lower the CO2 levels and then the blood pH would get stabilized.
