Question

explain the breathing mechanism in human beings​

Answer 1

Explanation:

The process of taking air into and expelling it from the lungs is called breathing. The action of breathing in and out is due to changes of pressure within the thorax, in comparison with the outside. ... When we inhale the intercostal muscles (between the ribs) and diaphragm contract to expand the chest cavity.

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.
