⦿ Mechanism of Breathing In Human beings.

During Inhalation The air enters through the Nose [ Which is The gateway of air ] to the Lungs. The nose contains sticky substance called as Mucus which Traps the foreign dust particles preventing them from entering our lungs. After that, air Travels to the Pharynx then leads to Trachea. Here, Trachea gets divided into two smaller branches Called as Bronchi which Again leads to the lungs. These branches further divides into Small branches known as Bronchioles. Here, At the end of Bronchioles, There are small air sacs called alveoli. This is the place where Oxygen is absorbs and released to the blood, forming oxyhaemoglobin.

Diaphragm has main role in inhalation and exhalation. When The diaphragm Stretches down, Inhalation occurs and At its vice versa exhalation happens.

The breathing in human beings takes place through the organs called lungs. The taking in of air rich in oxygen into the body during breathing is called 'inhalation' and giving out (or expelling) the air rich in carbon dioxide is called 'exhalation'. Both, inhalation and exhalation take place regularly during breathing.
