What is the role of the chemosensitive area in regulating the respiratory system?
What is the role of the chemosensitive area in regulating the respiratory system?
It regulates the oxygen levels in the blood
It controls the rate of breathing
It controls the depth of breathing
It controls the pattern of breathing
Solution
A chemosensitive area is situated adjacent to the rhythm centre which is highly sensitive to CO₂ and hydrogen ions. Increase in these substances can activate this centre, which in turn can signal the rhythm centre to make necessary adjustments in the respiratory process by which these substances can be eliminated.
