Answer 2

'Respiration' is the process where the two gases are exchanged – 'oxygen and carbon dioxide.'  

Answer: Option a)  

Explanation:  

• The respiration function aims to successfully move the two gases and enable gas exchange. This 'exchange of gases' occurs at the small alveoli that are present in the lungs and also in the capillaries that surround them.

• The process through which the 'air enters' and 'leaves the lungs' is known as ventilation. The oxygen is taken to the lungs and the blood 'carries it to all the cells' in the body, and the carbon dioxide is taken out of the lungs and expelled in air.
