Breathing is described as an alternating action of active inhaling air into the lungs followed by a passive exhalation of the air. During an inhalation our diaphragm and intercostal muscles will contract allowing the chest cavity to enlarge and draw air into the lungs. During an exhalation these muscles relax and air is forced out of the lungs.
Healthy breathing is an involuntary action which gets adjusted automatically by the body to maintain a normal gas exchange. The coordination of ventilation occurs in our ‘breathing control centre’ (medulla and pons of the brainstem) sending a constant supply of information to make fine adjustments to maintain adequate ventilation.
