Question

What is the chemical control of respiration?

Answer 1

Chemoreceptors:

1. Respiration is controlled by the concentration of CO₂ and H⁺ and the changes in these concentrations are detected by chemoreceptors.
2. They are present adjacent to the respiratory rhythm center in the medulla region of the brain.
3. They monitor the pCO₂, pH, and pO₂ of arterial blood.
4. They are highly sensitive to CO₂ and H⁺ concentration.
5. They send signals to the rhythm center for making necessary adjustments and taking remedial actions.
