What is the role of the chemosensitive area in regulating the respiratory system?
  1. It regulates the oxygen levels in the blood
  2. It controls the rate of breathing
  3. It controls the depth of breathing
  4. 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.
