What Are The Main Factors That Affect Normal Breathing?

Normal breathing is restricted by stretching of the thoracic walls and lungs, a drop in the H+ and carbon dioxide levels, an increase in oxygen level. Normal breathing is triggered by the relaxing of thoracic walls and the lungs, a decrease in the oxygen levels, and an increase in the carbon dioxide and H+ levels.

The main factors which affect normal breathing are –

  • Level of carbon dioxide in the blood
  • Level of H+ in the blood
  • Stretching in thoracic walls and lungs
  • Level of oxygen in the blood

Several other factors too are known to govern normal breathing such as chemicals and emotional state etc.
