can someone tell me what is the mechanism of respiration?

Taking in of oxygen-rich atmospheric air and exhaling out of CO2-rich alveolar air is known as pulmonary ventilation or breathing. For further details on the mechanism of respiration, kindly refer to lesson 2; Chapter 17 of our CBSE Grade XI biology study material.
