Physiology of  the respiratory system is a follows:-

  • As a person inhales, the diaphragm contracts and moves downward.
  • The space left in the chest allows the lungs to expand.
  • Muscles in the ribs also help enlarge the chest cavity, pulling the rib cage upward and outward.
  • Once the lungs expand, air moves in through the nose and mouth.
  • The air travels down the trachea and into the lungs, allowing a person to breathe.
  • The exchange of oxygen and carbon dioxide occurs before exhalation.
  • When a person exhales, the diaphragm relaxes, the lungs recoil, and the air moves out of the lungs.

Ventilation is commonly referred to as breathing.

  • It is the process of air flowing into the lungs during inspiration and out of the lungs during expiration.
  • The air moves through the passages because of pressure gradients that are produced by contraction of the diaphragm and thoracic muscles.
  • Individual alveoli have variable degrees of ventilation and perfusion in different regions of the lungs.
