Question

The respiratory centre may release motor impulses of faster breathing due to?

Answer 1

• The respiratory centre may release motor impulses of faster breathing under the influence of adrenaline, stress or lower amount of oxygen.
• The overall effect of adrenaline is to prepare the body for the ‘fight or flight’ response in times of stress, i.e. for vigorous and/or sudden action.
• Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye, redistributing blood to the muscles and altering the body’s metabolism.
• In case of lowered oxygen, the respiratory centre stimulates faster breathing to compensate the oxygen loss.
